Remote System Explorer modify Object Filter to show library names

I use temporary libraries for holding projects that begin with a specific prefix (PWA*).

If I create a Library filter for "PWA*" I can filter to these specific libraries but I have to scroll through all the objects to find the source files.

If I create an Object filter for library "PWA*" + Object Type "*FILE" + Object attribute "PF-SRC"; I can see all the source files but I can't tell which source file file belongs to which library.

I would like a way to combine these so that within the filter all of the matching libraries are shown and then expanding them will only show the source files within the selected library. Perhaps a modification to the Object filter option to enable or disable showing the library level.

Creating:
1) Expand System
2) Right Click Objects
3) Select New "Object Filter"
4) Specify Library: Partial Library Name with wildcard
5) Specify Object Type: *FILE
6) Specify Object Attribute: PF-SRC
7) Click option to show / group within Libraries
8) Click Next
9) Name the filter
10) Click Finish

Using
1) Expand desired System
2) Expand Objects
3) Expand the created "Filter" to see all the libraries
4) Expand a library that is shown to see all the source files within that library
5) Expand a source file within the library to see all the source members within that file.
6) Double click to Edit a source member
