Employee bank account data sync between HCM and Financials

For those of you who have both PS HCM and Financials, I would like to know if you use the integration broker to sync employee bank account data (for payroll and expense report reimbursement direct depots) from PS HCM to PS Financials. Is automatic sync and automate update to the bank data in PS Financials even possible? If so, is this only valid if we have PS Expense module?

we currently have employees set up as vendors and use an external expense report system that feed the expense report data into PS AP to pay the employees. So, we set up their bank account info separately in PS AP in the vendor record. Wondering if we can use the payroll bank data from PS HCM to systematically update from PS HCM into the AP vendor record, bank account data. we probably can, with custom interface development but wondering if we can leverage the integration broker sync between HCM and Financials. Thanks!
