[GNC] How can I change the account type from asset to fund?

[John Haiducek]

Hi,

I have an account that is currently an "Asset" account with the commodity
set to USD. I want to change it to a mutual fund account with the commodity
set to VMFXX. VMFXX is pegged to the dollar so this is theoretically simple
to do (none of the numbers on the transactions have to change). But when I
edit the account, the commodity field is non-editable and the options
available for the Account type don't include Mutual Fund.

I've heard it suggested to delete the account and transfer the transactions
to a new account, but gnucash won't let me select an account of the desired
type to move the transactions to.

Is there another way to achieve this?
