How to make information in card "scrollable"

I’m using the atomic-calendar card which displays my Google Calendars. I would like to be able to constrain the height of the card, but then be able to vertically scroll through the different days to see future appointments. Ideally the title of the card would remain static, almost like an embedded iframe?

Is there a way to do this? I could see the same functionality being useful for a shopping list card etc.

Did you ever get this to work?
I’m after a similar effect for a grid card overlaid onto picture-elements
