Sort by custom column in Windows Explorer override <Name>

We are using Solidworks 2017 - PDM Standard (Always stay a year behind right?) and are just now making use of the custom column sets in PDM.  I have added a variable and associated column for a variable, PBS (Product Breakdown Structure), as a way to sort which subsystem a part is located in.  We opted for this over a complex part-numbering or multiple folders on the off-chance a part can be found in multiple subsystems.  The problem is, that while we can sort by PBS in the column in Windows Explorer, the <Name> property is overriding that sort.  Here is an example of it supposedly sorted by PBS:

As can be seen, the 220 - Driveline are not grouped together but the part/assembly names are listed in order.  Is there a way to override this?
