Add tags to objects on whiteboards

We use tags on Features and Requirements for grouping items across product lines and between 2 products that connect but are separate applications.

We currently use a non-Aha product as a digital whiteboard that allows tags which means double-work for transferring over to Aha. It would help streamline our process for planning/brainstorming if we could just tag a sticky or other object in a whiteboard with the same tag on the Feature.
