Allow different number of days to be selected with multi-select on new registration

We have programs set up that require parents to select different numbers of days based on the room/rate. Example - 2 days full time, 3 days full time, 5 days full time. Each one has a different minimum/maximum day selection set, which works fine when a parent is selecting only 1 room. If the parent signs up a 2 day room and a 5 day room - selecting 2 days for the 2-day room and 5 days for the 5-day room - when Allow Multiselect is set to Yes at the category level, the parent is unable to complete registration because they get an error message stating that they must select less than 2 days. The Multi-select feature currently only works correctly for selecting multiple rooms with the same min/max day selection set, e.g. 2 5-day rooms or 2 2-day rooms.
