File browser window's default save format needs decoupling from the UI file save format

I have to set up my blend files to output exr for cryptomatte purposes, and I also have to save each image manually as a jpg after making tweaks in the compositor. Sometimes I have to save 5 or 6 versions, and each time I have to manually swap the file browsers save format from EXR to JPG and then slide the quality from 90% back to 100%. I generally need to do this around 50 times a day.

It would be much better if the file browser defaulted to whatever format was last used in the file browser, rather than being whatever’s set in the UI file output.
