Custom revision note numbering

[Christiaan]

For construction documents we don’t use standard consecutive lettering or numbering. Instead we use a system that progresses as the following example:

P1, P1a, P2, P2a, P2b, P3, P3a, C1, C2

 

Please provide support for this as doing it manually is very prone to error.
