[Elecraft] P3 Macros - MEM to MEM Copy? MEM Editing?

[Byron Peebles]

Has anyone come up with a reasonable means to duplicate a Stored Macro 
in the P3/SVGA?

I am interested in loading 48 memories with Macros that are all over 
100-characters and many of them are very similar with just a few 
characters different.  Because you need to type every one, this is 
tedious.  Even editing one requires you use a destructive backspace to 
get to the characters to change.

Is there a better way?
