Quick Connect for Bowden Tube into Nexruder?

Happy Camper here-just finished upgrading MK4 to MK4S + MMU3.  Works great after tweaking filament sensors on both units.

Question - is there such a connection that allows the Bowden tube from the MMU3 to be easily removed from the Nextruder to allow the printer to run in non MMU mode (turn off MMU in MK4S “settings”)?  Now I unscrew the Bowden tube fitting to do this.  A quick connect for the Bowden tube would be awesome.  I haven’t found such a fitting yet.

I only disconnect the tube from the fitting, leaving the fitting in nextruder. Have only done smaller prints so far, but works ok

This is how it should be done. The PTFE tube is already quick connect. There is no need to remove the fitting itself - just press the collet to remove the PTFE tube. Once done, push the PTFE tube back down into the fitting where the fitting will grab and hold in place. Simple.
