Enhancement suggestion for LODIMGCLG OPTION(*UNLOAD)

In IBM i v7.2 it is my understanding that only one image catalog can be mounted at any time to a virtual device. If this is incorrect then the rest of this RFE invalid and can be closed on that confirmation. But if my understanding is correct I'd like to suggest an enhancement to the LODIMGCLG OPTION(*UNLOAD) command.

Currently as the command stands today the image catalog name (IMGCLG) is a required parameter when loading or unloading. For the load this is perfectly understandable. But if only one image catalog can be loaded to a device then allowing unload based on the device name would be a possible feature. A new special value for the IMGCLG parameter could be added that would only be allowed if also used with OPTION(*UNLOAD) and a valid device in the DEV parameter. I would suggest *MOUNTED as this special value.

Use Case:

Usage would be as such:
This command would then unmount whatever image catalog is currently mounted to OPTVRT01 regardless of what the image catalog name is.

    The requested function is not a candidate to be PTFed to existing releases, but it is on our team's list to try to get into the next major release.

    In V7R3 you can load multiple image catalogs at the same time, no idea if it is limited at V7R2 (just try it).
