Sync Slash Commands with one Guild

Hello, I have a test server which i use to test my bots, I am new to sapphire, and by reading the docs, I couldn't find a way to make the app sync the commands to a single guild/server. I do not want to sync with all servers as I noticed that is slow and takes a few minutes, whereas when i sync with one server (my server) it's almost immediate. Can you do that in sapphire? Please help
