Compare central model to previous exported model

Revit
1

Hi
Wondering if there is any way to compare a central model to a previous version of the same model after you have done a revit export?
Have tried the ModificationTracker.ModelComparison node from Data-Shapes but seems like the PreviousVersionDocument input doesn’t work.
Can’t link the exported file to the central file either, so can’t compare model to link.

Any ideas?
Thanks

That’s the one I tried, but it doesn’t say anything about a central model and I also can’t get that script to work.

hint:
open your central model, creating a local file thats detached, name it 8-8-2019…rvt
