Never seen anything like that. Here's why:
Metallic cartridge:
-deprime/size
-prime/charge
-seat/crimp
Shotshell:
-Deprime
-Prime
-Charge powder
-seat wad
-drop shot
-Pre-crimp
-crimp
-taper crimp
Now many shotshell presses combine a couple of those operations, but it is very difficult to simplify the process to a point that doing it on any existing single stage or progressive meatllic would be possible.
If you want to make your own tooling to do shotshells on a metallic press, you have my blessing.
