Wire 2 CAT 6 jacks in series

I have 8 network runs from wall jacks to a patch panel in the basement. I want to extend a couple of jacks so that I connect another jack that I’ve added to another room. I know it’s not ideal, but essentially the two jacks would connect into the same port on my main switch also in the basement. What is the best way to do this? I have a keystone punch down jack but think it’s probably not good to punch another cable in there. Should I use a wall plate with screw down connectors with two cables? Or a double wall plate with 2 punch down jacks and wa switch?
