Converting Vacation & Sick time to just PTO and correcting fields, formulas & ytd

Our company renews vacation time on each employee's individual anniversary date.

So the accrual method of vacation & lump sum of vacation hours in sage options do not work for us.

In addition, we have recently switched from seperating Vacation & Sick Time, it is now one category, PTO

I need help cleaning up Sage from the old payroll fields & calculations, formulas etc. and switching over to the new one.

Right now it is all showing up on paystubs with incorrect calculations etc.

All I want is PTO used and PTO remaining for fields on the paystubs.

I doubt Sage will be able to calculate our unique way of doing it, so as long as I put in the correct begining balance, Sage should be able to keep up from time card data from that date on correct?

Help?!
