When using a dataset to define the choices in a form question, we should have the ability to apply filters. Otherwise, the wide-open dataset will include far more choices than necessary.
For example, if I create a form for approving sales commissions and select the sales transactions dataset, the dropdown will include people from as far back as the data goes who are not with the company anymore. It would be nice if I could apply either a date range filter such as "last 12 months" or filter on employee status = active to narrow down the list of possible choices.
As a workaround, I've been creating pre-filtered datasets specifically for powering forms, which is very inefficient.
