You have done it right by re-unifying the dual carriageway as there are no
physical barriers. It is unfortunate that the routing engines currently
don't support this kind of restriction (multiple via ways) which is fine
according to the wiki. Did you try to reach out to the routing engine
communities? Maybe they are not aware of the shortcoming and can implement
it.

Cheers,
Martin
