Ability to add multiple stocks to a portfolio at once

[iatenine]

I would like to be able to add more than a single stock at a time, either by enabling Shift-select + "Add to portfolio" or allowing a full watchlist to be added as a single batch. I understand this would likely mean they would all need to be added at equal quantities but that seems like a perfectly fair trade-off

I would have a screenshot example but right-clicking prevents screenshots, at least in Ubuntu 18.04 so that may or may not be a separate issue
