How to save an edited MOGRT for use in other projects?

For example, I've got some lower thirds created by editing a MOGRT that I'd like to quickly reuse in other projects, without having to retype the info.  But if I copy/paste an edited MOGRT between projects, if I take the 'source' project offline, the copied MOGRT goes offline also.  

How can you reuse a MOGRT that's been edited in your project?    

PS - I tried duplicating the .aegraphic file to a new folder & importing, but that failed.
