[Feature Request] | Able to select own portfolio to be analysed.

[MaximilianSoerenPollak]

A feature that I want to implement since quite a while.

It would be nice if we could also be able to select what stocks we have in our own Portfolio, and then do the calculation based on that instead of recommending stocks.
Wanted features:

-Be able to select own stocks
-Be able to select how many you already have
-Same calculation as already is being done, should be done on the portfolio

If you can think of any more features this should have just leave them down below.
