how to autosubmit correct answers outside of drag and drop

Can it be done? I'd prefer not to have my students do anything unless I have to. On success, I'd like them to just advance onward, like I use in drag and drop slides. I've created a few very simple advanced actions (yay...took months, and they're still so infinitely minor), but can't think of a way to make this happen.

My present interactions are click boxes on words, with hints and praise. I could use all drag and drop, I guess, but I think working in a variety of ways with the same words will reinforce it more strongly for these guys.

Maybe if I have to, a green image that I tell them means go on? Like a stoplight?
