Update Subsets dynamically - Formula driven Boolean

It would be nice to have the subsets updated dynamically using a formula driven boolean linking to the subsets as a formula, just like how we have the option to link Display Name to a formula in a module. 

This would certainly eliminate much needed efforts of running the action every time when we have to update the subset. This option along with the current feature of updating through actions would make the feature and, model building more efficient. Model builders would look for ways to automate and scale the model with the formula driven subsets which can be updated dynamically.
