Keying and Reversing video

I teach high school video production and this year went all in with Rush as our software for the students who are in the Level 1 introduction class. These are kids new to video editing so Premiere Pro is a bit too much for them. I used WeVideo since the pandemic which saved the day as they could work on any device. Now that I switched to Rush though the lack of a Chroma Key and Reversing Video is a bit of a bummer. Seems pretty basic that most editors, even web based ones, offer these simple tools. I see there has been requests from the community for years about a green screen... is there any update on this?
