How do i Un bold certain Items in Grep Styles?

i have several different cases i'll need this. hte on came across advertencia ¡atención!.  how can bold advertencia , not ¡atención! below picture shows how have it. shown below both words bolded.  not want atencion bolded in case.  time has ¡ ! in want not bold.  if shows atención (without ¡ ! ) want bolded

simple ¡\u+! should work, if word in caps, surrounded ¡ , !.

a bit wider version: ¡\u*?\l*?! (mix of upper , lower case letters allowed)

or use directly ¡atención! if word should affected.
