Currently one can use #### to be replaced by numbers, it would be nice to have an equivalent for letters (low case and high case separately). Adobe Bridge has this feature and is quite handy for some of us.
Note: There's currently a workaround in XnView to somehow get this but the downside is that it replaces the numeric enumerator.
Add letter enumerator
