Currently requests to the bulk endpoints for building blocks (e.g. bulk-upgrade) run into timeout issues, because all selected building blocks are processed sequentially before generating the response. This easily leads to timeouts for those requests when bulk-processing multiple hundreds or even thousands of building blocks.
It would be helpful to have an endpoint, which does not wait for calculating the response with a state of each of the building blocks, but rather only accepts the request and responds back immediately. The bulk operation (i.e. upgrade) on the building blocks can then be further be processed asynchronously in the backend.
