[GNC] Investment accounts - maintain ongoing balance only

[Scott Soderling]

I use GnuCash for all my personal finances. I have a number of "retirement"
investment accounts. I receive monthly multi-page statements for each
account from the bank, showing every transaction (buys/sells, interest,
dividends, capital gains, etc). Now that I'm a senior, I have to withdraw
monthly amounts from these accounts, which are transferred to a checking
account.

I really have no interest in tracking all that data in GnuCash. I can see
it all in the statements and/or through my online banking. What I am
interested in doing.....  create GnuCash accounts for each investment
account, so that I can enter transfer transactions each month to my
checking account. All I need to do in addition to that is update the
current value of the investment accounts, say as of the last day of each
month.

Opening the investment accounts and giving them opening balances is easy.
I'm now looking for suggestions going forward regarding updating the
current value of each account monthly. That is, I don't want to set up sub
accounts for every stock, mutual fund, etc and then have to track
share/unit prices, just to come up with an account balance. I just want to
enter one "adjustment" type transaction for each investment account, once a
month, to make it balance to my monthly bank statements.

Appreciate all ideas... thanks!
