I am trying to generate calendar and calendar_dates file for GTFS. I have School trips that follow one schedule for MTThF and a different school schedule for Wed. Along with this we have local bus service that operates on all 5 weekdays.
Can I create one serviceid for all local routes with 1,1,1,1,1,0,0 for days in service, one for Wednesday school service 0,0,1,0,0,0,0 and the last for MTThF school service 1,1,0,1,1.

My question is will GTFS then make trips in 2 service IDs active on a certain day?
Without that I actually have to generate duplicates of trips for each service id
