service request must inherit the account id of the order

I have a requirement to create a sales order but the order must be associated with a SR, which is created to the open the pick applet available in the "No. SS" applet field in the "Order Entry - Order Form Applet Dashboard (Sales)"; this part was modified with the next configuration:

• adding the NewRecord user property in the "Order Entry - service Request Pick applet"

• modifying the picklist "Service request PickList"

but I require that the service request inherit the account associated with the order.

what way I can resolve this issue without affecting the standard functionality?
