Is there no auto-rename if file already exists, same name?

[sdavidhicks]

I would like Xnview to rename files automatically if I'm saving and a file with the same name already exists. I can't find this feature. Is there a way to do this? A yes or no answer will suffice. thanks

In Batch rename you have an auto-rename (button "Duplicate..:" in "Batch rename" dialog). In normal (single) file rename, there's no such option.
