MMU3 filament unload - filament slips back to far and cannot be grabbed anymore

On filament unload, it happens many time that the filament gets unloaded a bit to far. I have identified that if you use a autorewind solution, this may happen more often. But also with stock equipment this may happen. The filament stops behind the pulley axis, so the pulley cannot grab it anymore.

With the upgrade to MMU3 this issues increased, due to less moving resistance.

A solution would be, if there would be a possibility to configure a pause time after the unload before the idler moves to the next position. The filament would then be held tight between idler and pulley and the filament movement (and also some pull momentum from the spools) would be absorbed.
