Is there a way to customize existing Work Management Templates?

[Shan Kotta Prakash]

Just wondering if there is a way that I can customize the existing JIRA Work Management templates, so that I can have a predefined set of Tasks and a custom workflow statuses while creating a new JIRA Work Management Project.

So that my team can choose this custom template while creating a project. 

Any information regarding this will be helpful.

I would like to know how to do this as well as we have some users that take that line literally (and reply between that line and the email header). Their message is ignored and we have to go to the support inbox to find out what they wrote and then copy/paste into the comments section of the ticket. Admittedly, this issue is more user training, but it would be better if we could change it to "Do not modify the text below this line when replying".
