Next view label in api

I'm writing a macro to create a drawing document with several detail views and section views. I'd like the macro to automatically assign the next view label to any created view, much like the normal user interface does. The information I need is available in the "Sheet Properties" (on sheet RMB -> Properties) window shown below. Does anyone know how to retrieve the "Next view label"?

I've gotten CreateSectionViewAt5 to automatically assign the next view label by passing "Nothing" to the SectionLabel argument. In VB.NET, my code looks like:

sectionView = swDrawing.CreateSectionViewAt5(0, 0, 0, Nothing, SwConst.swCreateSectionViewAtOptions_e.swCreateSectionView_DisplaySurfaceCut, Nothing, 0)

If the "Next view label" in the Sheet Properties window was V, then this code creates a view named "Section View V-V".

CreateDetailViewAt3 doesn't have the same behavior. Passing "Nothing" or an empty string simply creates a detail view named "Detail View ".

detailView = swDrawing.CreateDetailViewAt3(0, 0, 0, SwConst.swDetViewStyle_e.swDetViewSTANDARD, 4, 1, Nothing, SwConst.swDetCircleShowType_e.swDetCircleCIRCLE, True)

I could simply add a user input for each detail view, but that's fairly clunky. Any insight on the problem would be helpful.
