Absence Management: Can We Use A Fast Formula To Adjust An Absence Balance?

Summary

We are looking for a fast formula to credit back days to an absence balance

Hello,

We are looking to see if there is an available fast formula in Absence that will adjust / credit back days to an absence balance. 

What we need to do is the following:

Under a certain circumstance, we will credit back travel days to the annual leave balance. 

Annual Leave Balance Before Leave Take: 30 days
Annual Leave Requested: 11 Days
Travel Time Total: 5 Days <== to be credited back to the staff's annual balance

30 days - 11 days = 19 days balance after annual leave request
19 days + 5 days = 24 days balance after travel time (days) determined and credited
