[Feature Request] - Add exercise to Fitness Template without sets having data

[ChocolateDarkMatter]

Problem: Currently when creating a template if you add an exercise that doesn't have a record yet you get the message "Only sets that have data will be added"

Request: If possible please add an option, maybe an environment variable, to make it possible to add exercises that do not have a record yet.

Purpose: I like to create/define my workout routines beforehand. With the current method it makes it a bit cumbersome to experiment with new exercises.
