I-model workflow

Here is my planned workflow:

1. Publish I-models to Bentley Map mobile (IOS)

2. Survey crew makes redlines on said I-models.

What next? I thought the I-model could be brought back into Microstation as reference file. This doesn't appear to be possible. What can you do with an I-model?

I have a fair amount for time invested in this endeavor to find out the I-model is a dead end. Based on the help files found in SS4 this is or was possible (see capture below):

If I understand this correctly the help files for this topic are NOT accurate. The I-model is a dead end in its self. The life cycle is closed once the file is published via Microstation?

Any ideas?
