Function automatic ID

Hello Stéphane,
I am not talking about the ‘Capella Id’ that we can see on the ‘Expert’ tab of the Property view.
For each project, one defines one nomenclature to identify every functions.
For the moment, I am handling these in one of my project by putting the function ID in the summary of the function.
However, this raises some issues,( the main one is the impossibility to check that an ID is unique with Capella). So I was wondering if anyone here have already faced such problems, and if it exists a few tricks that will ease the management of functions ID with Capella.
Rgds,
