WAD - now I get it!
One potential way around the SH3 Commander problem is to have orders in the Date folder one month before they are to be implemented (I know of few people who have more than month-long patrols). You could then change the visible tab to say 'Kaleun Eyes only, not before 6 Jun 1941' or similar. That way they can 'open' their orders when they receive the radio message on the correct date.
Suboptimal, but workable...
