Limitation to Aliasing Why ?

[simoncn]

Aliasing allows multiple physical tags (the source) to be treated as one logical tag (the target). It is a "rename" operation, not a "copy" operation. This is important if the source tag is produced by MinimServer's fixed mapping from ID3v2 or iTunes tags, and the fixed mapping name doesn't match the name you're using for other tags such as FLAC. For example, you might want the ID3v2 TPUB frame to be treated as Publisher instead of Label to match existing usage of Publisher in your FLAC files. In this situation, you wouldn't want to retain the Label tags.

You could get close to what you want by doing the following:

1) Add an alias definition for Work:Group
2) Add Group to indexTags
3) Use the renaming facility in indexTags to rename the 'Group' index to 'Work'

The problem with this is that each Group is limited to consecutive tracks. I have some music where the movements of a Mass are interspersed with other pieces, so I can't use a Group for these works. Do you have this situation in your library?
