How to set setup shipping methods and change order’s existing shipping?

In woocommerce 3.4.3 I simply want to setup different named shipping options. For example “Shipping Method 1”, “Shipping Method 1”, etc. No price is necessary. Also, after the option is selected during checkout by the customer I want to be able to change their selected shipping option when viewing the order in WordPress -> Woocommerce – Orderes. It could not be more ridiculous.

I can manage to define “Shipping Method 1” by renaming Free Shipping in Zones as shown here: https://temp.extremehosting.ca/trash/rename.png
OR
I also can install some “Advanced Flat Rate Shipping” plugin that allows me to define some custom names as shown here:

But when editing an order after its placed, I cannot simply change the shipping method used to one of my defined shipping methods as shown here:

Why? Why is it so difficult to simply select a different shipping method for the order after its placed? I’ve tried creating custom plugins with something like this but I can only have one plugin and therefore 1 custom shipping method:

Whenever I try to select a different shipping method for the order in the admin I never see my defined Shipping Methods? Why? It could not be more stupid. It does everything under the sun accept allow me to simply select how the order is shipped.
