Exceeding characters in question feedback

I am building a quiz and I select immediate feedback, and seem to be exceeding the maximum # of characters allowed for this feedback method.

The content is finalized, and I cannot revise the feedback to make it shorter, so I'm trying to find an alternative. What would be the best way to show a long feedback message to a question? I've tried using "set text block" but that does not seem to work, and it seems like a lot of work to put together an additional page just for feedback. Ideas? Thanks!
