Segregation Pools copied year to year

is there a quick and easy way to delete pools that no longer have a balance in the following year.
i have a fund that is segregated for accounting purposes. the prior year a number of investments were sold, but it also continued to hold quite a few. so i have copied to prior year policy rather than start a new one, but now i have a lot of pools that are not needed.

oh i should say that each of the assets are segregated in different % between the 6 accounts.
