Pre Billing Acceptance: Transaction Date

We have activated the Pre-billing acceptance.

The system  stamp the TRX_DATE which is the Customer Acceptance date into the ra_interface_lines_all.

Is there the possibility to avoid this?

In our case we risk to create invoice with incorrect sequencing:

For example:

1 on date 22/07/2015 the customer service accepts the order 1 and the lines go in ra_interface_lines_all with date 22/73/2015

2. on date 23/07/2015 the customer service accept the order 2 and the lines go in ra_interface_lines_all with date 23/07/2015

3. the customer service do the invoice for order2 with default  date 23/07/2015 ---> the invoice 200150001 has transaction_date 23/07/2015 and gl_date 23/07/2015
