Approvals with Multiple AOR Types

I want to set up an approval where for a specific set of employees, the approval should go to one AOR type, then another AOR type. There should be one approver from each AOR type.

For all other employees, only one AOR type is sufficient.

If I set it up like this, either in SINGLE or in PARALLEL, the approval is sent to ALL AOR types at once. I'd like it to send to the first AOR type, and then go to the second AOR type for approval.

Is there a way of doing this without setting up an additional approval participant? Because a second participant wouldn't be relevant for a lot of use-cases, e.g. where I only want to use one AOR type for approval.
