Suggestion/Request: Add the ability to use existing Adversaries as Templates when creating new one using the Content Creator

[Badelatsche]

Pretty much the title: I would really love the function to create a new adversary by using an exisitng one as a template. For example if i just want to change some flavour or a single attack i dont need to type/click all the characteristics and actions again.
Can probably be done already just by copy pasting stuff in the data file, but might be a nice feature for the less code inclined :)
