expense report account number - automatic split

I am new to iExpense and as I am going through the setup steps, I am wondering if there is a way to automatically split an expense item to two different account numbers.

Example:

I created a expense report template. It has an expense item called "meal". I assign it a certain GL account number.

When the user uses the template to create an expense report and selects meal, it automatically goes to this GL account number.

I want to know if there is a way to split the cost of meal 50-50 between two account numbers, all in the background without user intervention.
