How to set Form request input date to system date if Orch Input Date is blank

I have an Orchestration with one of the inputs being a Date. This date is mapped to a form control on a form via form request.

If the Orch input date is blank, we would like to map system date instead.

Is there an easy way to do this where we can set Default Value to System Date instead of using Rules where we first check if the Orch input has a value or not and then proceed in two different paths.
