Here's a thought...
You only need the tens entry in the Action. Each action would call the same list, a data list, which would be 0 to 9, and would then be added to the calling action. For example, say action 9, whose value is added in the "tens" digit. That way you could have "9" & "0 to 9" to get 90 to 99. This might break Ken's minimalist rule, though.
