Linking MathCAD custom properties in EPDM

Is it possible to link MathCAD's custom properties to an EPDM data card?

I've tried the obvious of creating a data card and adding attributes with the block type of "CustomProperty" for file extension xmct.

However the data card is blank when I select the MathCAD file. Am I missing something?

Thanks,

Adam
