Render Queueing?

Hii There,

I often leave my PC to render when I'm off to school, work or bed. (my PC is a bit slow, so I want to maximise the videos I can put out)

However, often the video is done in a few hours, leaving a lot of time (and energy) "wasted".
Is there an option to have a render queue?
I want to have 4 projects (which are nearly identical except for some titles, artworks etc.) rendering.

I know I could just open 4 instances of HitFilm, but that would slow down the PC too much (or eat up all RAM).

In After Effects, I used to have 4 copies of the same project, edit it as needed, stuff it all in a render queue and go to bed or something.
