Add cli_chgrpmem command in order to add/remove 1,000+ users to/from a group

The current PowerHA release does not allow to add a group with 1000+ ID (verified with 1023 and 1246 IDs): doing so, CSPOC produces "Command is too long" error. Increasing CSPOC internal buffer to 32K does not help (debug iFix "dbg40041_a" was tested).
Such capability is required while adding a new group and the most of the existing IDs in PowerHA env. are required to be the members of that new group.
Because the group membership for each ID is strictly individual (we have dozens of groups ...) it is not easy to craft a simple command to change the group membership for all user IDs - we have to modify the group list for each particular user ID via "cl_chuser" command on per-user basis. Pls note that, PowerHA does not have cli_chuser command, therefore this is out of CSPOC, while doing that via SMIT HACMP i-face is not possible for so many user IDs.
Because PowerHA dev team was not able to craft "cl_mkgrp" which can process 1,200+ IDs (the debug iFix produces the same "Command too long" error above), the debug fix "dbg540041" was released to add "cli_chgrpmem" command into a list of CSPOC commands: it helps to add (and delete) as many IDs as needed into the existing group via a simple 1-liner.
"dbg540041" iFix was installed and "cli_chgrpmem" command was tested and verified to work. Now need this to be incorporated into the next PowerHA 7.2 Service Pack and have that command available upon updating to any subsequent PowerHA release and TL/SP.

    Support Team,
    Pls review and process appropriately. PowerHA has no tools to work with groups which contain thousand of users. The existing cluster command "mkgroup" produces the error while creating a group with 1,000+ users and there is no other way in PowerHA env to add users at a later time but only to do that on per-user basis, and if server has a big number of groups then we have to store the group set for each individual user in order to change user's properties which is not a trivial task and may incorporate the errors upon execution.
    Also, PowerHA does not have cluster-level commands "cli_chgrpmemp / cl_chgrpmem", while adding such command helps to remediate the problem by changing the 'group' properties (group membership) instead of doing that on per-user basis. What's really convenient is that, even for large groups it is possible to split the group members into a smaller groups use cluster's "chgrpmem" command several times to add 10,000 IDs easily.
    The existent command set in PowerHA does not allow to do this, leaving customers like me to struggle with per-user properties' change, which takes time and is not reliable because of a variety of groups for each user.
