Line Extension

I have a keg of cream soda in my two tap kegerator. I have 25' of line to serve the soda. I was wondering if there was a way to create a disconnect so that I could change out the lines between 25' and 7' for my beer. The barbs in my tower are a PITA to take a hose on and off of so I was looking for an easier way. I already know there might be some residual soda taste in the left over line, but that isn't my main concern right now.

Thanks!

If it were me, I'd get a second beer line disconnect and a second party tap. Just swap out the entire set up instead of changing the lines.
