Importing and retaining variables

I searched just now on this topic and was hoping SL2 had a feature where by you could define a set of variables (either manually within the application) or via file import, as well as the capability to import updated values. From there, one would define those variables embedded within text anywhere I need them (ie text to read on a slide/layer, state or within a quizzing Q). None of this is possible?

I've built a course for new hires with lots of facts and figures about staffing, how much the division represents of the total organization, how one location compares to another etc. All these values are static text, resident within text boxes. I have an offline Excel file I update and it provides #s and %s I need.

I have an indexed sheet in the workbook which identifies the location within my .story file i need to edit but I'm just editing static text. I was hoping I could define these 'variable data tokens" and reference them anyway for display or calculation purposes within the course. Import new values on whatever frequency I need, republish and Bam, Done.

Not happening? :(
