It would be a nice addition to Revit Schedules to have OR filter capabilities similar to what has been added to normal View Filters. This would greatly increase are filtering capabilities, especially when scheduling items from Linked Models. In our case we often generate Revit based drawing lists that include elements from linked models, but often do not want to include items from all linked models. Also reducing the need for Shared Parameters for simple filtering and organization.
