Add Class option to Drag and Drop Sections

It drives me absolutely insane that I can’t target drag-and-drop tags with classes or IDs! The drag-and-drop system has potential, but the current implementation is very weak. Adding class and ID selectors would resolve a lot of issues, or at least allow developers to make more viable band-aids until the system is improved.

It’s super disappointing that this was requested almost a year-and-a-half ago and HubSpot has still not responded.
