Post Icons per forum

[Bad Bunny]

I'm not a coder here. I am hoping someone that can code would find a use for a plugin that would allow one to set different post icons per forum if desired. Ideally, I think all forums would use the same ones, with an ability to make a forum override the default selections and use it's own icons.

Optionally, even something to allow a style to use different post icons would be a decent alternative.
