How to assign cards to a role vs a specific person

[Marc Pfeiffer]

I have butler automation set up to add a specific person to many recurring cards for tasks that need to be done regularly.  I would like butler to assign these cards to a "Role" and then on a more global level assign the Role to "Person A".  In this way in case Person A disappears I can assign Person B to Person A's role and the cards should get done versus me having to update all of the individual butler recurring tasks/automations.

Is there a way to do that and if not how can this be added as a feature request for Butler?

I learned this from this from Felix. Have a card named “name of role” with the member assigned. Use action assign member in turn and use the target icon to point to the card using a card link. 

This is where I learned from
