ACA - R081161 Average Hour calculations for employees not working a full year

In reviewing initial test runs of the R081161 UBE, we have employees who started mid-year and they are calculating the average weekly/monthly hours (based on the processing options) as if they worked the full year.  Is there a predefined method to handle those cases?  When we run the UBE for an ALE, can it accomodate employees who worked a full year and those that worked a partial year?

Thanks,
Andrew
