is it possible using automation rule to assign checklist tasks based on custom field value?

Using the automation rule features, am I able to assign checklist tasks based on custom field value?

For instance I created a rule like this:

when custom field "Card Owner" is set to "team member name", assign the item to member @teammember name.

What I want is that all of the checklist items in a certain checklist (which is already part of the card when the card is created from a template) will get assigned to the team member who is selected as the value for a custom field called "card owner"

Is this possible?

The rule is currently not working for me.
