Add own metadata/tags

I was thinking if some people intend to build a larger portfolio with a high number of stocks adding your own tags would be an amazing feature for both the discover tab and also your own portfolio. It would make searching for diversification categories or industries you may be setting yourself, and when/if better self serve data analytics of your portfolio is available (another potential suggestion) you could create your own charts showing the % split of stocks across the categories you have set.
