I copy and reuse portions of a design, I'll copy and the designation numbers follow the copy (for example: I'll have U1 and R2, then copying you end up having to U1's and two R2's, I don't want that.). There are sections that I'd like to re-designate (or clear designations to U1->U? for example) or have Altium renumber the designators.
1) Is there a way to make a selection and clear the designators?
2) Is there a way to clear designators in a sheet or redesgintate only a sheet?
I think I remember that you can use a 'special paste' and paste a design without designators labeled. I don't want to know about that way, I'm not a fan. I'm running 15 right now but could update.
