Improve the link between release templates and the actual release

I would like to have a link between the release template and the release which I then create with this template. Sometimes I realize changes when working on refining the release phases. Then it would be great to have the ability to update both, the template and the release coming from both sides. Otherwise, I need to update them manually. 

Also, the description and attached files should be used for the created release in my opinion. Then the information is more valuable.
