Adding dice expression to number

[Bobson]

I'm working on implementing some things from Legendary Games' Ultimate Rulership for a game I may be running, but I'm stymied by the best way to implement a Consumption modifier of 1d4 or 2d4. Since consumption is a numeric value, I can't simply append "+ 1d4". And even if I wanted to use it, there's also no equivalent to a regular character's "Specials" or "In Play" tabs to add an ability to describe the random cost.

Anyone have a suggestion? Is this at all possible? Is this why there isn't already a UR data file?
