There are some same questions about, “how to save player’s @command setting on NPC”. Or “how to autoload @command for player on login”.
Using same @command again and again on every login is kinda annoying. The idea is, save the common used @command and let players to choose it. It’s just need simple OnPCLoginEvent label in a NPC then executes the listed @commands.
This is simple example to save player’s common usage @command by using NPC. Because this is just an example, you can expand it later. Maybe to allow player’s preferences for @alotid 607, but edit it yourself.
Here are some screen shots about this sample script.
