CNC/Laser: M3 unpause R parameter

As I couldn't find any information about this, I'll put this topic into the wishlist:
When using CNC or Laser mode,
M3 S123turns on the spindle/laser with a rpm-seep/intensity of 123.
However, after pausing with M226, I' like to turn off the laser, otherwise I'll leave a big long burned line while the head travels to its parking position.
G1 already has the R parameter to return to the last coordinates when unpausing.
M106 also has an R parameter to spin up the fan to its last power setting.
So it would be reasonable to add an R parameter to M3 that restores the last set spindle-rpm or laser intensity.
This probably also affects tool changes and related parts in the firmware. Spindle speeds & direction and laser PWM.
That sounds very sensible. I have added it to the firmware work list.
