I just discovered that single file rename (pressing enter on the contact sheet) doesn't allow to use variables, and multi file rename still doesn't allow to use variables without the use of either {fbas} or {seqn}. I understand it is to prevent file name conflicting but I often have the problem that I have to reuse previous filename I store in {subj} but to rename to {subj} is not supported.
Can or will there be any help with this?
