Automations: Assign to-do's based upon record assignee

As a user, I would like to automate the assignment of work by also creating to-dos and approvals.

With automations, I can trigger an action to create a to-do when I assign a feature but I am required to pick a static assignee for the automation to function. The assignee is typically the feature assignee in my case, so I would like the action to be conditional and use the current assignee that I just selected.
