Adding background image to embedded cards
I'm having a bit of trouble trying to figure out how to add a background image to a card that is powered primarily by beast mode calcuations. I've endlessly searched the forums and have not yet been able to come up with a solution. What I have is a matrix with 4 quadrants that need to be color-coded and labeled. Here is what I've tried so far and why these options are insufficient:
1. App Design Studio - This card displays correlation coefficients which can only be calculated via beast mode. As far as I have researched, the Design Studio will not allow table caclulations to be the main source for the colums.
2. Custom svg files - I pretty much run into the same issue as the point made above.
3. Adding html code into the beast mode - Doing this would effectively take away our correlation coefficients, so this option is out.
Anybody have a solution or experience with handling something like this?
EDIT: I'm also adding that this card needs to be embdedded, which elimates the option of adding a background image to a story board.
