TimeTrex Time and Attendance

Hello,
I've been using timetrex only for time control, not for payroll, I would like to start using it for payroll too.
Is there any way to get into timetrex the already accumulated social security payments? or do I have to start from scratch?

thanks in advance

Cesar
