Hi Sharon,
Great question! Have you considered using a global feedback activity for this? You can set up a feedback activity on the front page, then link to it from a block on any other page, or even add it as a link in the top nav.
We use global feedback for our Academy courses here in the Community, and have a Behind the scenes video on how to set this up which is part of our Feedback and choice course. It's a slightly different use case but it might meet your needs?
Interested to see if anyone else has any suggestions for this too!
