Deductions for 1/1/2020 - How will you make a mass update to HRMS if you haven't been tracking deductions in HRMS?

We have HRMS and Timberline.  We use a 3rd party for Benefits Open Enrollment and monthly maintenance and enrollment. 

Every year we have to ask IT to go in to TL and edit the benefits deductions for all the Adds, Changes, and Deletes for up to 14 different benefit offerings.  As we have grow over 450 employees IT doesn't think they should be responsible for manually updating the TL database.  

Is there a way to import the deductions into HRMS so that we can utilize the BAS push integration to update Timberline?

Thanks,

James
