Hi,

I am wanting to create a custom fill were the series follows an incremental series based an numbers and alphabet characters (Unit 1A, Unit 1B, Unit 1C,....and so on, then the same repeats but starting with Unit 2A, Unit 2B, Unit 2C.....etc.
It is problably a question that has been answered before but I could not find it searching the past threads.

Any ideas would be highly appreciated

THXS
