It takes several minutes to add a single package

This doesn’t do what I want either though, because what I want is to have a project for my particular data analysis task, but within that project it has all the “infrastructure” one often needs directly available. Now if I could say something like --project=. --project=@data --project=@optimization --project=@database and have the current project be the . directory but the various other projects are “stacked” on that, it might make sense. (BTW: I really like having a built sysimage with all those things, so for now that’s my main solution)
