Feature request: tag default value (constant)

[simbun]

I have a tag called ALBUMTYPE that serves a very similar purpose, although I make sure it's always populated with numeric values that I translate to literals using MinimServer's tagUpdate functionality:

@ALBUMTYPE=1
=ALBUMTYPE=Studio
@ALBUMTYPE=2
=ALBUMTYPE=BestOf
@ALBUMTYPE=3
=ALBUMTYPE=Live
@ALBUMTYPE=4
=ALBUMTYPE=Archival
@ALBUMTYPE=5
=ALBUMTYPE=Compilation
@ALBUMTYPE=6
=ALBUMTYPE=Soundtrack

I did it this way so it's trivial to change the description going forwards.

@simoncn, is there a way to have the tagUpdate process match a missing tag/value (I've tried leaving it blank)? If it were possible then all GioF_71 would need to supply is:

@ALBUM_RELEASE_TYPE=
=ALBUM_RELEASE_TYPE=Studio Album
