Creating your own JPA generation templates

Intellij does tell me how to create a template but I want it to be JPA specific. File->settings->Editor->File and Code Templates->Files click on the + and name your template.

What I want is for my template to do is what it already does however with a few additions.

1) char is defined as a String and in the @Column it generates columnDefinition = "CHAR"

2) Getter and Setters use Java 8 Optionals.
