Yes. It is possible to selectively control the 'opening' and 'closing' for various types of accounts. Usually, a '+' is mentioned in the top-most entry indicating that all the account types are allowed for posting. Now, for the GL(S) accounts, you will need to specify the period which needs to be opened. This ensures that all the account types are open for the current period, indicated by '+,' and only the GL accounts are open for the previous period.

Select account types can also be opened or closed for a specific period; select accounts within an account type can also be opened or closed.
