Why in the conversion of dwg's in solidworks over to 2D AutoCad am I losing the last .000 in filename?

I recently upgraded to 2017.  This was not an issue before, in 2016.

Now when a Solidworks drawing file

ie…  H1234DE.001-S0002.000.SLDDRW

Is saved as an Autocad DWG

It becomes… H1234DE.001-S0002.DWG

Why does it now strip away the “.000” ????

This is an important part of my clients file naming
structure! (It means the file is at revision ZERO!)

In this situation a zero does not equal nothing,

it means something.

EDIT:

I just submitted a ER
