Bulk device confirmation for Device Authorization Flow

I have a use case to setup several IoT devices and do not want to store any secrets on them. So I used Device Authorization Flow for that. However, the user can confirm the devices only one by one. Device auth flow is not scale in IoT case.

Is there a way to confirm multiple devices with one user action during the browser flow?

I also need this usecase, any solutions you found so far? @a.sirak
