In Simscape-Multibody-Contact-Forces library is there a Face to Face Contact Force Block?

I am new to Simscape and Multibody contact Forces.
So, I know there is a Face to Plane Contact Force Block, where the plane is assumed to be much larger than the face.
But I need a Face to Face Block, where, in my case, both faces will be identical in size.
Is this available or even possible to create in Simscape?
The simpelest way to look at it is: I need to model two dice sliding on a plane towards each other, where any face on one dice might contact any face on the other die, we can assume at this point that the contacting faces are oriented parallel to each other.
My untimate model would be much more complicated with multiple dodecaherons, rolling at arbitrary angles, but the above will suffice for now.
Any advice would be appreciated.

Hi John O,
While the Simscape Multibody Contact Forces library could be used for these types of collisions, a better solution would be to use the Spatial Contact Force block that ships with Simscape Multibody. I recommend you attach a Point Cloud block to each die with points representing each of the corners. Between each pair of dice (die A and die B) place two Spatial Contact Force blocks. One Spatial Contact Force block will connect to the Point Cloud on die A and the exported geometry on die B, the other will connect to the Point Cloud on die B and the exported geometry on die A.
