Request: Change of "Track number assistant"

The track number assistant is a very useful function and use it very often. But I'm missing the function for other tags like all other tarck/trackid/episode/episodeid.
I'm working a lot with MP4/MKV of TV shows and at the moment I have to do 2 side step by creating track numbers with the assistant, then formationg tag->tag for copying the track number to tvepisode tag and then removing the track number.
Not very often but it can happen, the track number is in use and then I have to re-create the track numbers.

Would it be possible to get a drop-down for the target tag for numbering?
Adding another checkbox like for "track" and "disc number" would require lots of space and with the drop-down-version (to select track, disc number, tvepisode,...) you can save space and extend the functionality. Of course it would be nice, if the last selected drop-down element will be saved automatically after using it.

Additional check boxes could be hidden/shown with the drop-down selection to clean up the window even more and just showing functions if the use is possible.
But this is just an additional idea.

I'm pretty sure not this many people are using the counter to create mutiple numbering tags at the same time (like track number and disc number at the same time which is theoretically possible now). So I hope my idea is not colliding with the current functionality and usability of the assistant is its current state.

The track numbering assistant has its virtues of resetting the counter under specified conditions.

If you want a simple ascending list of numbers in a different field from track and/or discnumber, use an action of the type "Format value" and as part of the
Format string: %_counter%

Yes, and this is what I want for "tvseason" and "tvepisode" too. Because I get data with seasons in single folders and want to create tags out of the folder structure - like with music (disc number/track number).
