not a reporting services guru, but for regular scheduled jobs, i can create a job which does something, like send an email or update or whatever, that runs every day, but only does something on 110 days after some specific date calculation.
can't you do the same in reporting services? send only if data meets a certain criteria, and schedule it to run every day forever(so it effectively SENDS 4 times a year,but checks whether it should run ever day)
