How do you pause Ramio Plus, resume from there on Mini?

If I'm watching something on the Roamio, pause it, go to another room with a Mini, how do I resume watching on the Mini from the paused point?

Selecting the same channel on the Mini just goes to that channel live, taking up another tuner, which doesn't seem very smart of it. This is especially annoying if I'm 10 or 15 minutes behind in the buffer on the Roamio.

Is this possible to do?
