Default Colour Mode on export

When designing, i sometimes prefer to design in CMYK, since the colours better represent how it will print, also some of the colours are a lot more appealing visually (such as the green and cyan) to it's RBG counterpart.

But when i export it as a jpg, it keeps exporting to the document Colour Mode which is usually CMYK... but i almost NEVER want a JPG to be CMYK.

Setting RGB as the default export mode, or even export to the last used colour mode, would make exporting images so much quicker.
