Thanks for the kind feedback, blackone, very much appreciated.
The XPresso Tag can be stored as preset, and the lists could be a UserData Interface.
However, if that is too much work, perhaps use Maxon’s suggestion site or ask the developer of Magic Replace to add this feature to the plugin.
If you have problems with XRef and Takes, the best way is always to check with the Support, or use as well the Suggestion form as well.
Since I don’t know what your core target is, I can’t look further into this. Let me know if there is anything else, I’m happy to look into it.
