Thibaut,

Do you mean interface similar to Figure 2 here?

https://www.xmlmind.com/xmleditor/_distrib/doc/profiling/the_solutions.html

I cannot find screenshots of Oxygen XML on their site. Is it similar?

Maybe simple solution will work: Now branch inset dialog allows choosing 
branch and setting inversion. I propose to add radiobuttons: Basic and 
Advanced and leave existing settings in Basic part. The Advanced part 
will contain just edit field for logic expression on existing branch names.
