Could we get the ability to add additional layers of assignment to a CTA?

I would like there to be extra layers of assigning a CTA.  As an example, right now I can assign it to a role and then assign a default owner.  What if we could add the ability to add another layer of assignment so if the first option to assign is not valid for that customer, but a second option would be valid, I would rather assign it to the secondary option that just a default owner.

So if an account has a Technical Account Manager, I want the CTA to go to them, but if not I want it to go to the Account Manager and if no Account Manager then I want it to go to the Account Owner and if not yet assigned an Account Owner then assign it to the Net New Sales Manager (Default Owner).  A checkbox to add additional layers of potential assignees would be great so I could customize by CTA.
