Open Items Managed Accounts

I use F.13 for OI clearing for customers and vendors. However i can not use this transaction for automatic clearing of employees accounts which are under one GL account. Appreciate if you advise the transaction to clear employees acoounts by one post. Now i am using F-44, but i have to enter each employee account (a lot of lines) and clear the balances. the best way would be to enter GL account and clear by one post.

thank you in advance
