A record can have a source record position. If the record is produced by the stream processing then it points to the record that was processed. Otherwise, the source record position is less than 0. This allows the see the causality.

Currently, there are some records that have a source record position but that are not produced by processing the record.

To Reproduce

Is your feature request related to a problem? Please describe.

To quickly select several elements within a diagram, I would like to use shift+click as a common way and very known from many other tools.
