I have a tiny little problem... Which has significant consequences. I know how to upload mods to the Nexus and upload them, I know how to upload mods to Steam, along with scripts/textures/etc/.

But AFTER I already uploaded a mod on to steam, HOW do I attach new scripts to said mod, that people can download via the Steam Workshop? Is there some way to do this? Is there any way to update the scripts and stuff other than ESPs on something that's already been uploaded?

Not sure rather this goes in Creation Kit or Mods... But seeing as how it isn't directly related to the Creation Kit put this here.
