Edit Orders + Super Orders + Create Customer +Create Orders

I've got those first three installed and running but I need the ability to create an order for a customer on the backend so as far as I can tell my only option is to install the create simple orders add-on correct? If so, then I'm a bit confused by the files I need to add/modify. For instance my current admin/add_customers.php file looks nothing like the one in the create simple orders one so I'm a bit lost as to what files I need to edit etc. All I want to add is the create orders function...?

With all the mods - -
If they have code for the same files as others, then that code must be copied/merged into ONE file
