Natural Account Segment Security in GL, but not in procurement/expenses

Content

Is there a way to have natural account segment security and have it only apply when viewing general ledger data? I have payroll accounts I want to lock down,so users cannot view the general ledger details. I want the users to be able to enter requisitions or expense reports charging these accounts. When I enable segment value security on natural account users cannot enter requisitions charging to the locked GL accounts.
