How should we improve Labels in Planner?

Joanna Parkhurst We create tasks that are relevant in a number of different ways to our teams.  For example, I might ask someone from a team containing say 30 people to resolve a customer technical issue.  This issue might be relevant to other customers too so it is worth thinking about that.  It may also be something that we might then blog about to generate work in this regard.  If it is such an interesting issue then we might discuss it at our team meeting.  We used to use asana and we would tag the above task with the following tags/labels:

• Customer query (we would then collate all tasks tagged as such onto a customer query workflow board)
• Jeff's tasks (we can then identify all tasks of any nature assigned to Jeff)
• Ongoing product development (a board full of ideas to develop in future)
• Blog ideas
• Team meeting agenda items

One of the weaknesses on planner is that I can't tag tasks with multiple tags as per the above to slice and dice the whole pool of tasks to arrive at individual task lists or marketing, blog, technical lists as described above.  We would therefore like to have as many custom tags and labels as possible.

Thanks
