Description of the bug

After completing a layer in one color, the toolhead freezes for a little over a second before parking the head. In this time, the toolhead may* stay on the printed part, causing blobs by oozing filament. This seems to be caused by "G4 S1.500 ;" command in the CP TOOLCHANGE START block. However, it does not seem to be able to somehow change that by any settings in the slicer.

*Additionally to this setting not being changable: Using two toolheads, the first toolhead goes to the wipe tower, then does the 1.5s dwelling and then docks that toolhead while the second toolhead does the dwelling on the printed part and then is docked directly. I am not sure, if there is another option in the slicer I am missing for that.

Issue originally found by reddit user "finestaut", just matching my issue I had the same day. I am just writing his findings here, to be sure it's seen for Slicer development.
