Workflow boards should allow "tag" based assets filtering
So basically, I could say in the board that this board's data needs to show only information from specific tag assets.
For example, I could make a board for the Finnish support team, which shows only assets with the tag "Finland". This would simplify how much data is shown on the one board.
This is possible on per-board basis using Board Data filter. Board data filter applies to all rules and only includes assets that first match that filter, before evaluating any filtering in the rule.
