When it comes to Dispatch BUZ default's to all orders to Installation, as Installation is a common type that it used, but this may not be relevant to you or you may want it to automate to another status pending on the answer selected in the Order.
The first step is to create an "Inventory item" for the status you require
Settings → Inventory Items → + New Item
Below is 4 examples but you dont need to set them up exactly the same, the key factor is the Installation type down the bottom.
Once you have set up the relevant Inventories that you required, go to you Group Options and Download your Extra's
(you can add this to a product but if the sales rep or customer isnt consistant and selects 2 different answers it will not work and may not have the correct status)
Go to Settings → Inventory Settings → Group Options → Download current layouts → Extra's
Add the required question you have and answer's with the appropriate code attached (In red)
You may want to assign an installer to the status created
Settings → Workflow Timing & Tracking Settings → Installers tab (current view)
Once you have linked the installer to the required status the dispatch type and installer will match the selected choice in the Extra's
