@zelio This has always been possible under macOS. Most people with this issue are using Windows drivers that present this limitation.
In a future update we could maybe consider having a separate USB-MIDI device port dedicated to the editor (or if not possible at least let you dedicate an existing port to editor communication, which would prevent the port from being used for MIDI routing).
In the meantime you can leave the first USB-MIDI device port to the editor, and use the MIDI DIN ports for your DAW, as @frank suggested.
