Should documentation of 3Way DNA be categorized under One Name or DNA categories?

I have completed documentation of a 3 Way DNA confirmation.  I felt that the detail was best shown in Free Space.  The relevant profiles are linked back to the Free Space.  Patterson Smith Burton 3 Way DNA Confirmation 

The primary family name is Patterson.

I have not found any other work like this and wished to add a category for the documentation.  I used this hierarchy.

Category: Patterson Name Study

    Category: Patterson 3 Way DNA Confirmation

         Patterson Smith Burton 3 Way DNA Confirmation

You will note that I also have added a pending category - this is for cases where the DNA documentation is complete but the family file is not.

    Category: Pending Patterson 3 Way DNA Confirmation

Are there additional suggestions for the hierarchy?  Should all the material go under a Patterson DNA Project category that does not currently exist.  A Smith DNA Project does exist so this seems like an option.

The problem I have with this, and I seem to be alone on this, is that 

1. You are not confirming the 3 DNA testers, you are confirming a series of parent/child relationships.
2. A single triangulation does not confirm the relationship between 3 DNA testers.

I noticed a significant change to the help which now excludes confirming with DNA any shared ancestors.  

"The parent/child relationships in an ancestral line from each tester in the TG back to (but not including) the shared ancestral couple should be marked as "confirmed with DNA"."

Technically, you can "confirm with DNA" up to but not including the shared ancestral couple given the guideline...

"You will need at least three test matches (you and two or more distant cousins) who all match on the same segment of DNA to confidently confirm which ancestor(s) you have in common."

This is because Phillip and Katina are two of your distant cousins but since they are siblings, they only match 1 distant cousin.  If they could match to your sibling as well, the guidelines are followed.

Hello Philip,

Unlike Y-DNA, three way autosomal DNA confirmation is not tied to direct paternal lines or surnames.  

If autosomal matches could be categorized then it would make it easier to keep track of them.  Here is some earlier discussion of that:
