Yahoo Finance is generally great, inlcuding the portfolio features. However it'd be even better if users could move transactions / holdings from one portfolio to another.

For instance - I track my holdings (with transactions including sales) in one ('Current') portfolio. However this means that over time the portfolio page becomes very long and unwieldy, and current holdings are mixed in with previous (sold) holdings.

I have a separate portfolio for 'Previous holdings' so I can monitor realised gains etc. However to move a holding from the 'Current' to 'Previous' portfolio I have to manually re-enter each transaction, which is very time-consuming and can introduce errors.

It'd be much easier if there was an option to move a holding (or each transaction) from one portfolio to another.

Many thanks,
Lee
