How to export bus element signals out of model?

Hi,

I've recently created a largish size model (over 1000 blocks).

For the first time I've used "bus element in/out" ports to manage signal routing in and out of the various sub-systems.

This has been a revelation in productivity compared to the old method of using bus creator/selector blocks. The end result is much cleaner.

The problem is though, now I want to create the model interface and export these buses out of the model which are defined using the bus element out ports.

How do I do that?

Do I really need to manually create bus definitions again which exactly match the buses already defined in the model?

That seemes like redundant work with high scope for error does it not?
