Insert pause in Gcode for CM

Here’s a feature request, bump it if you like the idea!

CC - Allow M0/M1 message "toolpaths"

I’d like the ability to create toolpaths that consist of M0 or M1 plus a message. So, no object needs be selected, but the M command would be written out to the Gcode based on the order of the toolpaths being written.
