Add-on [PAID] Ability to exclude certain forums from the forum's RSS

Hi all,

I am looking for an add-on that will allow me to select specific nodes, and exclude them from my forum's main RSS feed (/forums/-/index.rss). Or if it's easier, create a new RSS file with only forums that I specify.

If anyone is available to do this, please PM me. Happy to have this add-on released publicly (I have seen a few threads by others requesting a similar feature).
