There’s no such feature in Rack. If I remember correctly this was proposed in the past and rejected. I’m not involved in the development but I can see two reasons it makes sense not to implement this. First: the use case you describe is very specific and it’s likely this feature would be rarely used. Second: when you’re filtering the module browser entries by developer, after you add a module to Rack and then open the module browser again, the filter is still active and it allows you to immediately add more modules by the same developer.
If you often apply this all-modules-by-one-developer approach, I guess it’d make sense for you to use stoermelder Strip. Check out https://patchstorage.com/platform/vcv-rack/: maybe someone there is using the same approach and has been sharing their strips. At least one developer (@Eurikon) has been doing this on our forum: Stoermelder Strip: Eurikon presets
