How to change General printing speed from PrusaSlicer ?

Hello, I was trying to print some tricky calibration models from MakersMuse to check how the printer is well calibrated, using a standard PLA. I set the SPEED from the LCD to 45% for the first two or 3 layers, and then to 50%, for the others, since it is a very precise object with almost n0 margin of error, and also because at 0.15 I noticed that my PLA is very dense, and not very fluid, so this could prevent under-extrusion. That was done from the LCD panel during the printing.

It worked and the object was printed without detaching from the bed and the tolerance of the printer was PERFECT. Well done PRUSA 😄

My question is:

- is there in the current PrusaSlicer 2.3.3 a way to set the M220 45% from layer 1 to layer 5 and M220 50% for subsequent layers in the dynamic print settings panel on right on the preview page ?

I have found only speed settings for details (infill, perimeters, etc.) but not a global way to change the speed corresponding to the LCD panel speed. I do not want to change or recalculate manually all the absolute items values for a slower speed.

- Do you know where is it, if exists ?
