Allow a 6 digit provider user to enter a future order for another provider

We have the need for a 6 digit provider UBL to be able to enter a future order under the ordering name of another provider. Similar to what a 5 digit staff UBL would do, they need the ability to change the ordering physician name and have the system reflect that they entered the order on behalf of provider xx. Many times our NPP assist staff and the MD by entering future orders on patients for the MD but want the order to reflect the MD entered so the results go to the MD. We could set them up with a 5 digit UBL but they shouldn't be bothered with having to login as a different UBL simply to reflect they are placing an order for another provider.
