Reference field for different capacity planning scenarios

We want to use estimates from capacity planning to feed into one of our initiative record worksheets in order to get an idea of cost (estimated hours x blended rate). This works in concept using the "original_estimate" reference field; however, we use more than one scenario to figure out initiative sequencing just as capacity planning intended. But this poses a problem: having multiple scenarios throws off the calculation because it doesn't know which one to point to as it only relies on "original_estimate".

Right now, we need to choose between having only one scenario for planning, as it feeds into our cost worksheet, or we have multiple scenarios for sequencing but no cost worksheet. The way to mitigate this is through reference fields for multiple scenarios.
