[Feature Request] Duplicate item suffix editable

[Monica-Wood]

Currently when you duplicate a record, it puts a 1, 2, 3... etc after the idno. Can a setting be created to change this to using letters instead. A,B,C or a,b,c.

Not sure what would happen if you get to Z (if you have that many duplicates), this might be a constraint on using letters instead of numbers.
