Can you add Stocks to An already existing pie?

I made a pie a little while ago and Iā€™ve found another Stock or two that Iā€™m thinking of Investing in, was just wondering if thereā€™s a way I can add them to my existing portfolio or if Iā€™ll need to make a new one which either way donā€™t think it should matter too much.

You can edit the holdings and click the + button or import a security held outside a pie.

I can appreciate that many want this but it is not something I would consider using.

I have certain good performing stocks both in and out of pies like #avon which I believe can continue to grow.I know that if I transfer it all into the pie Iā€™m likely to inadvertently sell some the next time the pie balances and reduce my position.
