Renaming output file with filename without extension

I try to make some renaming presets, but I can’t find a way to have filename without extension.

For example, for an image called “Image.ORF”, the filename token will be “Image-ORF” which is absolutely not what I want.

I just want to add a simple suffix to the output name, for instance “Image_D.dng”.

Yes, that would be great. I’d also propose selectable/editable separators.

Funny: If I untick “Rename” the output file is still called Image-ORF.dng

And if I export several tries with the preview, file are overwritten without any warning.
With the “instant develop” option, I get a warning and a choice to use unique filename… probably a bug.
