I have connected a Powerapps app to an excel table in OneDrive. The file contains a hierarchy starting with products and markets. I want users to be able to make decisions (notes) and write back to the data file. The trick is that I want it to scale based on where they are selecting in the hierarchy. So for example, if a customer has a region/product selected and enteres a note, I want all records that have that region/product to receive that note. If a user then decides to make more granular decisions (notes) at the market/product level underneath that region/product, then it overwrites any existing decisions there with the new ones.
