[arch-general] Is it possible to download only one single update from community-testing?

Hello, I noticed an update on community-testing which is not (yet) available in community repository. Is it possible to download this single package, without downloading full repository index and probably even updating everything to community-update? I looked at https://wiki.archlinux.org/title/Pacman, https://wiki.archlinux.org/title/Frequently_asked_questions#Package_manageme..., https://wiki.archlinux.org/title/Pacman/Tips_and_tricks, but it seems I missed sth. Kind regards Peter
