Benefits Program year period and plan year period not aligned

Hi,

Is it okay that the year periods of benefits plans different from the year period of the program that they are in? This is due to different policy years of the plans. Here is an example:

Holiday Purchase (Program) year period: Jan - Dec

Plan 1: Buy in hours for group A (Jan - Dec)

Plan 2: Buy in Days for group B (Jan - Dec)

Plan 3: Buy in hours for group C (June -May)

Is it possible to have plan 1, 2 and 3 to be under the same Holiday Purchase program?

Thank you!
