Drag a face from the reserve into any slot. Drag a slot's face back to the reserve to empty it, or straight onto another slot to swap. Edit the alias, case number, and art note inline. When it looks right, hit Export and paste the block back to me.
On representation: every con is a "con," so the only thing that can skew is which faces carry which roles — and who ends up in the innocent/decoy reserve. All 40 are visible at once for exactly that reason. My starting draft leaned a couple of faces toward on-the-nose reads (a flat-cap face as "The Wrench," a striped top as "The Splicer") — treat those as the first things to reconsider, not fixed.
