Functions ID

Is there a way to add IDs to the functions in Capella’s System Analysis? (just like requirements are expected to be ID’ed, something like F1.12)
Obviously they can be added manually, but I’m meaning a more automated process, like a field or similar.
Additionally if rules could be defined for the ID “numbering”, that would be very useful.
Thanks for any feedback.

Hello,
No that does not exist, sorry.
