Hi Bette,
Thanks for reaching out!
While this is not something that is currently available out of the box, it is a feature that has been requested by several users and is something we’re working on. I would recommend casting your vote for this feature over in our Feature Ideas Forum so that you can stay up to date as we move forward with this feature.
In the meantime, you could probably accomplish this effect using some custom CSS. We do not currently do customizations, but this article should help get you started if you’d like to give it a shot!
I’m sorry I don’t have a better answer for you at the moment, but please let me know if you have any other questions!
Thanks,
Jennifer
