I've also been looking for a way to get Memorized Tx entered without closing/opening the company file.

You can sort the tx by Next Date in the Memorized Transactions list (by clicking on the column header) to see what's next, but there's no way to select multiple items in the list and there's no way to automatically enter them. 

As you already know, when you select a tx and Enter it, you aren't exactly "entering" it.  Instead, the new tx is presented and you must then Save or Save New or Cancel.  This makes entering each Mem Tx that's due a 'multi-click' affair.

If anyone's discovered a way to enter Mem Tx without closing and opening the Company file I'd love to hear about it.
