Additional fields in change templates

Additional fields in change templates

I'm attempting to customize our Change Management templates and running into some trouble.  I'd like to add additional large text fields below the "description" field, unfortunately when I add the fields, they default to being one line tall and only extend halfway across the canvas.  How can I customize the size of the additional fields?

Also, can I customize the fields required for different stages?  Say I wanted to add a "proof of testing" field to the Implementation stage, how can I do that?
