Watchlist notes (simple but effective)

Something that would add huge value to me in plus would be a simple freetext note against each of the stocks on my bought/watchlist.

When scrolling through I would love to record simple reminders like:
‘buy on next dip’ or
‘keep at 20% of total holdings’ or
‘penny stock, beware’ or
‘congrats on the 10bagger’ or
‘in for the longhaul’

Thanks in advanced.
