Financial, Merit or Departmental Aid for current students?

I read an old post from a RISD parent that their child was able to secure several departmental awards that helped with tuition. My D is currently a freshman & doing very well academically/artistically.

But with a younger sibling heading off to art school too in the not-so-distant future, any additional $ is needed.

Does anyone know of or have experience with securing additional aid, merit or award $ once they’re enrolled at RISD?

Thank you!
