Maybe show a hint that a function has to be created manually first in the assembly editor.

Solution: It is necessary to create the function manually in the assembly window: right click -> create function. Maybe instead of the error message, a hint could be useful.

Thanks for catching this. At the very least we should prevent users from attempting to rename the undefined function.
