Ability to change feed rate

This might already be possible, but if it is… I haven’t found it.

When trying new filaments , you typically need to change temperature and print speed. Temp change is supported, but I don’t see any way to change the feed rate apart from using other software to export gcode. So, maybe a future version of the software will allow us to enter feed rates for 1st pass, subsequent pass etc… or maybe even just a percentage change that affects all of the built-in cetus feed rates by some ratio.
