No, it's not possible.

If you'd like to make a feature request for this, from the website's Help menu, select "Request a Feature" and follow the instructions you'll see there. I believe it's already been requested, so you can search for the card that seems relevant, and either vote for any suggestions that you like, or add comments if you have any improvements for the existing suggestions.
