It does kind of. You don't have to call in for an entire block. For reserves it's single days, day by day, as required. Go to the CCS, Scheduling, Sick Call screen and pick your days, one at a time or a bunch at once, either way you want. If you have a hard-to-get medical appointment in the middle of the next month, after the PBS award comes out you can use it to show sick for that day, even if it's weeks in advance. CP may not like it (a medical appointment is not an illness (Fordham University) or, why are you forecasting an illness in the middle of a reserve block two weeks from now?(Findlandia University)) but I've never been called on it. Works great! Health comes first.
