Currently in App Studio, when an application uses multiple datasets, the Filter component automatically sources from the first dataset in the alphabetical list. Unfortunately, there is no way to specify which dataset should power the filter.
This forces us to use workarounds that are not ideal. One method is to rename the desired dataset with a leading space to "bubble it up" to the top of the list. Another is to union all datasets into a single table.
Both of these workarounds could be eliminated by adding a feature that allows users to select a default dataset for the Filter.
