GL distribution over multiple fiscal period

Good day,

I want to know if it's possible to do the following, we are on 9.1:

Our biweekly payroll is not in sync with our fiscal calendar, this means that once every fiscal period, the first week of the pay is, for example, in our fiscal period 1 and the second week in our fiscal period 2.

When this happens they want the GL process to split the pay data between the two periods correctly. Is this possible?

Thank you!
