Eliminated Ability to Enter Holdings Directly in My Portfolios
I have used My Portfolios to track stocks and funds for many years. To do that, I want to edit the number of shares each month in each lot of the Holdings listing. This was always possible up until now. There are enough changes in the accounts that I do not want to waste time entering the transactions one at a time. All I really need to do is edit the number of shares each month for each lot of a given holding. I see from the comments trail that I am not alone in how I have been using Yahoo and in finding this new release to be unusable for my purposes. Please bring back the option to edit the number of shares in each lot directly. Barring that option, I will need to just get rid of Yahoo Finance since it will no longer be of use.

I would add to my comment that I don't need to track the cost basis, gains, etc. in My Portfolios since it is being tracked separately by the brokerages I work with. I used My Portfolios to pull together a summary of all the accounts.
