I would like to request a feature for the advanced filters. I would like to have the ability to exclude any task that has a scheduled start date.

The use case is that I have established a filter for any action item that is designated high or medium priority. When I look at the results of that filter, I want to focus on things that I haven't begun yet or need to get started on based on my changing priorities. For the actions that have scheduled start dates, I don't necessarily want to see them as they have already been scheduled to begin on a certain day. I only want to look at actions that have no set start date. I would fine this incredibly useful.

Thank you.
