I guess that once components are added here and approved, new components will be added in new places and renumbering will never be necessary.

But I'm still confused on where should I add new stuff.
They will not be as many as yours, I estimate only 2 or 3 lines.

In the space left before B5 comps start? In a new row, or after Last comp? After all B5 stuff? And where's that?
