Is there a way to define parallel Invoice approval to Application roles using SRC?

Summary:

Our requirement is to route invoices to General Manager for approval based on the BSV on the invoice line.

If the invoice has 1 line, approval is routed to the GM of the company in the BSV.

If the invoice has 2 lines, each to a different BSV, the invoice approval is sending the invoice for approval to each General manager in serial as opposed to parallel. We would like the approvals to be sent to all General managers at the same time and require each of them to approve before the invoice is fully approved. Currently, these approvals are being sent to each General Manager, one at a time, which presents an issue if we have invoices where, say, 10 lines, with different General Managers, get routed for approval in serial and causing significant delay in
