How to manage a different tax Service date during sales order entry

As far I know, till the A9x version in WS, there is no possibility to handle the tax service date in sales : only the sales order entry date is used (P42230/P42800) (X4008C tax server parameter).

Due to tax rules, the invoice date should be used for tax calculation for order coming from sales orders. In some cases, some orders have been raised for a while but have not been invoiced yet. So, the rate used during the sales posting will be the rate applicabel at the order entry date not at the invoicing date.

What procedure do you use to manage that case ? (we don't want to change the sales order entry date in all orders in pending)
