Stereo Rendering File Name - Number Padding after Camera Suffix

Hi Guys,

I’m rendering out a stereo animation. But the default Left and Right Camera puts a _L or _R after the filename. The problem I am having is that the _L and _R are going after the number padding, which makes it hard to load up into a compositing program. Is there a way to get the stereo camera name before the number padding of the file output? Thanks.

I can save the file as a R and L eye separately, but I just wanted to know if I can avoid that for convenience. If it is not possible right now, I can accept that as an answer.


I need the same, and beyond running renaming as a post render process or some pre render python script (if such a thing exists in blender), this field should have full access to some basic keywords / expressions / variables.
