How did you hear about us checkboxes

I wish there was a way to set up "How did you hear about us?" as checkboxes. They could check all the ways they heard about us so we know which advertising methods are being seen. Right now we have it set up as a fill in the blank. However, I have seen things where you can list all the ways an they can check all of them. If we could add our own list of ways we advertise such as facebook, instagram, tiktok, school flyer, Google search, referred by_________. etc. I would LOVE this!
