Does QB online track negative PTO balances?

An agreement was made to front an employee un-accrued PTO hours. I have entered the total PTO in payroll and QB notified me that the employee doesn't have that much accrued PTO time (as expected). If I run the payroll, will it show a negative PTO balance? Then in subsequent payrolls, will accrued PTO be applied towards that negative balance until the employee is in the positive? I know that I can manually add the fronted hours in the employee settings, but I actually prefer the negative balance approach so more PTO is not available until the appropriate PTO has been accrued. Manually adding the PTO hours also would result in the max yearly PTO hours being accrued early within the year, rather than maxing at year end. Thank you!
