Tree Support issues

I’ve been playing with tree support with great success. Two questions though:

  1. Does anybody know how to or if it is possible to change the main tree ‘trunk’ diameter? I’m not talking about the smaller branches.
  2. It appears that there was once an option to add or remove tree support infill according to the Bambu lab wiki page. I don’t see that as an option anymore. Has this in fact been removed on the latest release?

Take a look at this intro video note the time I have circled in red he talks about tree supports there. "Bambu Studio "Version 1.7 is here. It brings HUGE Improvements & New Features! - YouTube

Thanks for this. The added brim option for tree supports will be handy. I still don’t see an option to adjust trunk diameter specifically though.

If you scroll down a bit to ‘advanced’ - it’s there
Plus you can add wall loops as well…
