Process Payments is not getting enabled in the Standard Sales order header where as it is available

Hello Champs.,

We have a requirement to process the Sales at the store counter and also at the warehouse , for both the cases the customer makes the payment upfront we are able to achieve the payment for store orders through quick sales orders where the Orde lines immidiatly gets fulfulled but the for the wareouse orders although the pciking shipping needed we need make the payment and process then payment similarly to the Quick sales order ..

THe question here is can we also make the prepayment incase of Standard sales order where the line flow is Line flow generic if yes ..i am not able to find then process payment in then sales order actions LOV.
