Pause in G-code for Manual color change?

So, I've just finished building my latest CoreXY with yet another Duet 0.8.5, IR sensor and PanelDue with the Flexion Extruder. I'm interested in trying to make this do a manual color change. Is there any G-code that is supported in RepRapFirmware that I could put into my tool change code that would do something similar to the Pause button on a PanelDue?

I'm thinking if the G-code pauses for a tool change, uses M117 to display a message about changing the filament, I manually unload and reload the filament, and then manually resume the print. This would then allow me to "multi color" a print manually. I'm not talking a lot of color changes,but was curious if this was possible in the G-Code?

You can use M226 in your gcode file to cause the print to pause at that point. Put your M117 command either immediately before the M226 command in your file for printing, or in your pause.g file. You could also use M300 to make as beep, or several M300 commands to play a tune.
