Speed factor resetting during IDEX printing

Hey, dear peoples I have a slight issue with my IDEX machine.

So during printing with T0, I notice the extruder skipping, thus I turn down the speed to 80% using the speed factor. Print continues great.

Now a new layer and a toolchange, all variables switch to T1 and thus speed factor is set to 100% again (???), which I did not expect but for the filament in T1 is fine.

The problem comes with the next toolchange, where all variables are set to T0 again, except for the speed factor, which is specifically set to 100% again, leading to extruder skipping.

My question:
How can I keep the speed factor persistent?
1.) Either have it stay at 80% for the full print (so T0 and T1 will continue printing at 80%)
2.) Have the speed factor apply per tool (so T0 will print at 80% and T1 will print at 100%)

Is this possible?
And in addition, where to find the RATOS macro controlling this? Then I can modify and overwrite it unless anyone has a better solution, or if it is maybe an existing setting somewhere.

I looked around and no one seemed to have this issue. I expected the speed factor to not be tied to the toolhead at all.

Thanks in advance!
