CoPilot Follow Up feature pull from the same object of the original PowerList

When I create a follow up powerlist from a CoPilot the follow up list pulls from a completely separate object than what my original powerlist was created from. The reason why I create a powerlist on different objects is to use TAGs to send the emails from those employees and in the signature line. Because the follow up powerlist is on a totally different object I no longer have access to sending a similar template from the same employee to the customer. I am only able to send from the customer or account itself which makes not sense. Doesn't make sense as a customer to get an email from myself to take a survey for a company.
