it would be very interesting to use tokens in the output file names, for example if you write <filename>.png and the file is scene.max, the output path would be scene.jpg and if we also add for example <filename>-<camname>.jpg, it would be scene-Camera.jpg and if we also add <filename>-<camname><###>.jpg it would be scene-Camera001.jpg, these are some examples, could be also, the time, day, sequence, ....
I know that these tokens work in the state sets, but I don't know why they don't work in the simple output or in the batch render.
