Again, I ran into a problem. I have to select a few different areas to choose from in the category selection field which is visually shown in red, according to my content format publishing principle. But whichever of them will appear above the sender, the system is determined to be “alphabetical”. How can I do that? So for example I choose a, b and c, but the system puts a as a name. I want b to appear.

Developing custom code for custom functionality is beyond the scope of support that we provide here.
