Filter submittals by Trade Partner

Currently, submittals can not be filtered by trade partner, and there is not an option to assign a specific submittal to trade partner when a new form is created. It would be very helpful to filter down the submittal list to only submittals for one trade partner, as currently the only way to do this is by spec #, which has several challenges. A dropdown list of all trade partners on the project within the submittal form would allow you to assign a submittal to a specific company. Within the home view, there could be a column containing another dropdown that would allow you to filter by trade partner.
