No, you really can't do that. What you are describing would be a series of taps along a single cable. If you were to use one of the middle taps, the far (unused) end would cause additional reflections on the cable, giving you signal quality problems.
About the only way to accomplish something close to what you are describing it to put 2 jacks in each wallplate location, and run a cable from one of the jacks to the next upstream wallplate and another cable from the second jack to the next downstream wallplate. Then, install a short patch cable between the 2 jacks at each wallplate to form a continuous circuit. When you want to use a particular wallplate, you would remove the patch cable and plug your device into the jack that connects in the direction of your switch or router. By removing the patch cable, you've removed the "stub" that would cause reflections.
Having a lot of patch cables and cable terminations will cause some signal degradation, but if you do a good job on the connections and use good quality patch cables, it will be ok.
Personally, I would just home run a cable from every wallplate back to wherever your switch or router is located. Put a patch panel there, if necessary, so you only need to connect the cables that are being used to the switch/router.
