Within my original set of ADOS orders, is there a way to also include going to school and having orders for my MDAY unit?

That’s not exactly what I was getting at, I go to the schools through my MDAY units budget, but every time I go with my Unit ADOS has to cut a completely new set of orders that takes forever to start paying me. So when I bounce back and forth my pay is continually screwed up. I was wondering if there was a was to write my ADOS orders so that it has the dates they know I’m going to be with my unit and just “suspends” from ADOS or puts me on a break from orders without having to cut a whole new set of orders. It would just pick up back to the ADOS as soon as my MDAY orders were complete

No, you can only have one duty order in the system at a time, there is no way to "suspend" one order for another.
(You can't even input an order that overlaps another order by a day).
Also, your MDAY unit does not have a school budget, that's just one budget at state level that all units use.
Your pay should not be late: If you are on long term ADOS with just breaks for shorter orders for schools (and no non-duty day breaks), AND if your unit and funeral honors are doing pay in a timely manner, you will be paid mid month and end of month every time.

No, I was implying that the soldier writing and submitting my orders are taking the easy way out and Inturn screwing soldiers pay, I was hoping that they would able to write all the orders I need for that year at once
