Questions about tag formatting limitations

[eseb63]

Hello,

I would like to handle work rating, to see quickly which works i prefer among all those of a composer.

For that, i thought to use a WORK_RATING tag and tag formatting to concatenate the work name with it :

• i would need Work.displayFormat but work is not allowed
• i can't use Work.indexFormat because it combines multiple tag values to create one concatenated value instead of create multiple tag values, which prevents other settings from working (see https://forum.minimserver.com/showthread.php?tid=7504)
• using tagupdate works, but it would require to handle hundreds or thousands entries : it would be tedious, difficult to maintain, and i guess it's not recommanded to use such a huge file.
  

So, my questions are :
1) why is displayFormat only allowed for some tags and not work in this case ? would it be possible to add work in the allowed tags ?

2) you told me earlier that indexFormat was developped on the displayFormat model : i understand it was easier, but the goal is not the same ? while it's logic to combine multiple tag values in one for displayFormat, i don't see in which use cases it is useful to do so for indexformat : any example ?
