Can I extend this shape without building it again?

I’ve made this piece multiple times till I got the correct angle. However, it needs to be about 5mm longer to the red curve. I feel like I’ve seen tools (cage edit?) in rhino that might be capable of extending without having to rebuild it again. Thoughts, suggestions.

I think the fastest way is to explode and delete the right surface. Then ExtendSrf the open sides, Join, Cap. Should take less than a minute.

Thanks. I just thought there might be some tool I was missing. Like a Push-Pull option or something. Just trying to keep up my skills.
