You mean add a field to the infobox?

The problem is, when many of these things came out, they were in continuity. They still are - in their continuity. Current continuity is just another continuity. "Non-continuity" would refer to those stories which are explicitly no longer part of their continuity, retconned away, like Batman: Son of the Demon and other Earth-85 stuff.

That distinction simply hasn't been established yet for Prime Earth (New 52/Rebirth) so it'd be subjective and wishy-washy. And there are sorta-continuity stories, like intercompany crossovers.
