  1. What is your feature/integration request?
    I’d like to be able to provide parameters to a flow. The values in these parameters would be used to replace literals in Filters and elsewhere. I’d also like to be able to append the value of the of a parameter to a file name. I would like to be able to set the values of the parameter via a user query at run time or via a scheduling request.
  2. What problem would this feature/integration solve? It would enable users to use a single flow to change the behavior of a flow without changing the flow itself.
  3. How do you solve/workaround this problem today? I change the filtering in a flow to indicate which dates I want the process. I also change the file name so that the output is stored in a unique place.
