Yes, that is indeed how the groups works and it's quite logical, thank you
And your "NO_ACTION" is a good planning ahead, but I instead of creating some empty group, have made [and selected for ever] an useful action which clears all the tag fields that I don't use. So when I execute it, "nothing" important or irreversible for me will happen
But I was thinking about how to even further improve / workaround those needs of mine. My question is: is it possible to create [an action?] that will not set the whole field [format value] but add something to it, in the beginning or at the end?
Example:
I have empty GENRE TAG. I use one of my genre actions from "genre menu" list action group to put in it let's say "##44". But I also want to put a "##66", so that in the end [after taking two actions / steps] it would read like "##44 ##66". So after a regular "##44" [that changes the format value] I would have to use an "additional" defined "##66" [that adds " ##66" to whatever value already is in the field]
And I don't want to create "##44 ##66", aside "##44" and "##66", because there will be cases like "##44 ##66 ##70 ##80 ##90" and at the same time "##44 ##66 ##70" and "##45 ##66 ##90" and maybe also "##66 ##70 ##80 ##90" etc.. So the overall number of all the combinations would make a very long list. And I can easily remember what "##44" and "## 66" are suppose to mean, but I won't be able to remember the existence [or the lack of] of all the long combinations like "##44 ##66 ##70 ##80 ##90"
