Cache Settings

I'd like some ability to control the cache size -- either a maximum or to allow it to grow as long as I have some specified amount of space left.
What I'm after is for trans-muxed videos to stick around for a day or two. With kids in the house, we often let them watch half a movie on one night, and want to let them continue watching the next. I don't mind having to fast-forward to the appropriate spot, but I'd like to not have to wait the 10-15 minutes while my (very slow) PC transmuxes again.
The best I can tell, Serviio clears the cache daily (or at least when my PC reboots) and never keeps more than two transmuxed videos.
