How can I restrict Boards to today's items?

[michaelgutmann]

I would like to restrict my Eisenhower matrix to only show Today's items. Ideally, this would be a static board, but I'd be happy to also filter the general Eisenhower matrix to only show Today's items. I thought Today might be a tag that I can select, but this doesn't seem the case. Would someone know settings/configurations that would achieve what I am after? More generally, is the Today icon no tag? It would be useful it were from my point of view. Many thanks for your help!
