Save several images (different sizes)

Hi, I am quite new to RawTherapee, I would like to produce several images from my RAW image, one with original size and at least one more resized to something smaller (let’s say usable to send by email etc). I have seen such a feature in CaptureOne and I liked that. Is something like that possible?

So for example, I want to save the image in the original dimensions but also in 50% of the original. Ideally each to a different folder or maybe with a different name so that I could easily recognize them. And of course I would like to have that done automatically when I put the image to the Queue.

Batch-edit the resizing parameters (sync), send to queue.
