copy drum map from one project to another

How can I use a drum map from one project in another? The drum map manager appears to provide the ability to create new maps, and top open ones from a list of presets (in which my drum maps from other projects do not appear). From what I can tell, I have to tediously create in the new project a copy of the drum map from another project.

You can save drum maps in the drum map manager ans they will appear on your drum map list.  

Note that there is a really annoying bug:  After you save your drum map Sonar puts that name of a different drum map in the name box so if you accidentally click again you'll overwrite one of your other maps.  Cakewalk ignores all these little annoying, time wasting bugs and they never get fixed.
