This post is a continuation of my original question here: Custom Label with Autotext - Frame that wraps content?
I'm now to the point of customizing the out-of-the-box Zone Label 27 in GDL to get the frame around the correct content to match our company standards. I'm absolutely new to GDL, so it's not going great. Image below show what I'm after (which is having the frame around the body content, but not the header content, as shown in Room 101). The furthest I've gotten is adding "Style 8" to my options, but haven't figured out yet how to actually manipulate the frame lines, nor how to add a new icon to the list of options (see my goofy list of styles below):

Thanks in advance!
