In the modpack tab please add a button that you add a download link to a server.zip(in this case for technics) this would mean that people could use what ever modpack that want
and if you want to you and make a upload button like in the worlds tab.
-it would make it so you did not have to go thero all of the packs people are asking you to add.
and you could tie it in to how the backups works
