How do you change the pair of terminals on a contactor?

I have a pair of contacts on contactor which I originally wanted to be 73/74 and now I want to change it to be 13/14. The contact numbers are coming from the part number. I know I can edit the terminals through RMC Edit Symbol Terminals, but that is not "using up" the contacts from the part number.

Do I have to delete and reinsert the symbol?

Thanks
