I kmow that you can at max make the mod you create as esm format in version control depend on 2 official esms like skyrim and update .... But some mods will require the use of content from other dlcs and so have the dependency on them , so far as I know is not possible to add more so I would like this thread to discuss the possibilities of how toovercome this limitation , perhaps other modders tools like TesVedit could solve it ?
