Is there any way for me to “park” one colour of warp on a mill?

Question: Is there any way for me to “park” one colour of warp while winding on a mill? I know that those who use a warping board just leave the cone by the beginning of the path when they change colours, but I can’t see how this could work with a mill.

You can not park a yarn on a mill because it is always turning. You would get all messed up big time. I get messed up parking a yarn on anything. I always cut and tie.
