Sync elements in a container created within iTwin

For someone who needs to sync multiple models and group them in the same container within iTwin, we must attach all the models in one DGN file. This creates two issues:

1. Managing multiple 3D models locally can be difficult.

2. iTwin can’t sync DGN files containing a large number of 3D models.

My idea is to create the container within iTwin and define a specific container for syncing when selecting the DGN file.
