I've done this: I've added the people and the chain I relate to them on, with the DNA match being listed as "Jane (DNA Match) Doe" so that I can search "DNA" and find them all.
Not only would I prefer another method, but I'd like to color code lines I am unsure of, something we could all do so if we see (for example) a red line, we know to tread with caution as it may not be correct. Or another color to say "confirmed by paper trail". After a few hundred names, it can be confusing to remember who you have to keep working on.
