t would be nice if PowerApps supports Cascading Controls, and I think I need to refer namely to CDS being the data source. So, imagine my PowerApp will have a dropdown list for Contact in an Organization, it would be too bad to hit the dropdown list of Contacts - in data entry mood for a specific Organization, so see in that dropdown list all Contacts from All organizations. Naturally, such a dropdown control should AUTOMATICALLY filters Contacts those belong (related to) that organization only. that is why Cascading Controls Support is kind of a must.
