My suggestion for the "Intervention Order" is if you have it set up to where you have a response button that sends all the units from one station i.e
Station 1
Station 2
Station 3
My suggestion would be if you accidentally click the wrong station response button, say you pressed Station 1 instead of station 2, a quick press of the station 1 button again would clear out the Station 1 units.
First Click - checks the tick boxes
Second Click - Clear the tick boxes
Although it is very simple to just cancel out of the dispatch page and reopen it again, but if you have slow internet, or slow PC/Laptop/Mac that can be very time consuming.
