Allow a 2 step de-icing/anti-icing procedure like Type 1 de-ice followed by Type 4 anti-ice.
This a typical 2 step process, however you can not select so in GSX.
Currently, if you select "Request De-Ice" a second time, it will simply start application with the same fluid again.
A simple menu could go like this:
Select Step 1 de-icing/anti icing: Type 1 / Type 2 / Type 3 / Type 4 > Select Percentage: 50 % / etc. > Select Step 2: Type 1 / Type 2 / Type 3 / Type 4 / NONE > (Select Percentage: 50% / etc. ) > de-icing/anti icing starts
This way, the de-icing vehicles will not drive away and come back but simply apply both fluids.
