User Level EMP-USER-LEVEL

We aren't using User Level for anything right now and we would like to use it to record the Division that the employee works in. We were told that this is a field that Payroll normally uses for check sorting purposes. We don't need to use it for check sorting purposes. Will populating this field have any impact on payroll jobs if they aren't using it? i.e. for PR160 the report sequence is PL/Dept, so I just want to make sure there isn't any "hidden" sorting that would bring in User Level and impact payroll reports.
