PTFE Y Adapter for MMU3 and Side Holder

Has anyone tried using a PTFE Y Adapter on the Core One?  I use both my MMU3 and the single spool holder on the right side, and there has to be a better way to manage this besides swapping PTFE tubes at the extruder.

Thanks.  I found that a while ago and had an issue with the filament snagging on the festo connector. Looking at it again tho I don’t think I used the recommended print settings. I’ll try again.
