‘Add Note’ on individual stock page

Wondering if it’s possible to add a note :memo: to the stocks page. So when viewing an individual stock you could add some extra info of your own, such as price research or maybe a log of the ex-dividend Pay dates ?

Would be handy to do all that in the app rather than having to go away from it to where you have the info elsewhere. Would also mean people are using the app more making it their own which could increase user interaction.
Not sure on what would be involved in doing it so it may be a complete no no.

This would be great if you could also add notes (E.g. bought based on PE ratio) to a transaction too so that this info showed up in your activity feed.
