Split element costing at element definition level

Summary:

Hello, we have a requirement for payroll where 50 percent of the costs of an element go to one account and the other 50 percent to another

Content (please ensure you mask any confidential information):

Is it possible to set this up on the element eligibility page? I have tried using priority cost accounts but this does not automatically pick up the other segments like Cost Flexflied segments like Company, Department etc unless I enter them specifically.
Thanks
