Filter Survey Points

I have my survey with its points, chains, and DTM in Geopak SS3. Is there an easy way that I can export the points used for the DTM creation and then a separate file for the non-DTM points? Most (95%) of the points have the Terrain Model Attribute set to "Determine by Feature Definition". The other 5% was set manually. I looked at the filters within Survey, but I didn't think it would work for this scenario.

Any suggestions?

Thanks,
Ken
