Enable Azure Advisor recommendations to be filtered by tags.
I've seen tags recommended to help group business unit resources for budgeting purposes. Would be nice to be able to find ways to save money per business unit in that way (or identify wasteful ones).
The ability to filter Advisor recommendations by tags would enable greater recommendation granularity (in cost savings in particular) to maximize the benefits of implementing Advisor recommendations for business groups, major projects, etc...
(For transparency, I'm a Microsoft employee, but not on the Advisor team, and providing this feedback based on personal Azure usage experiences)

Thanks for your feedback. This is something we’ve heard before but haven’t prioritized yet. Any others, if you’re interested in this, please vote, and we’ll prioritize accordingly.
