Ability to use manuel email tasks within workflows

Currently we have the option to enroll contacts automatically via workflow into a sequence and there we then can create a manual email task where the email body is already pre-filled and the sales employee only needs to check and maybe add some documents to it before sending it out.

It would make it a lot easier if we could do that directly within the workflow creation as a action because then we don’t have the problem that a contact only can be enrolled into one sequence at a time.
We could of course create a task where in the body we note which email template should be used but this can lead to human errors.
