I am exploring the interface of DT3 and came across the (for me) new action
Tools → Batch Process → Execute script
I would like to use this to change the title of selected documents according to a fixed RegEx. Can I add a new script to the scripts listed there? And how does the script interface with the documents?
ps: I do know about the script “Rename using RegEx”, but I want to create a script which does always the same without inputting the RegEx.
