During the school year we can only setup funding drops by grade and date. However, if your students are importing from separate SIS scopes, we can set the initial funding schedule differently for each scope.
So, if you want to have two sets of funding schedules, you must:
A) Have two separate SIS scopes
B) Fully fund the students initially for the entire year
If you want to do additional funding drops, during the school year, and only fund certain students of the same grade level, then the only way to do it would be to fund ALL students and use the multiple manual adjustment tool to remove the drop from the students that you wish not to fund at that time.
