I can't seem to add preflop positional stats in the HUD. Is this a custom thing? The stats are in the popup as raise first in.

But the only stat I can add to the HUD is Raise first in (but not by position) such as EP, MP.

The way to do this is to add the regular stat (Raise First In), then select it and change its position in the Item Properties area to what you want to see. The options there are EP, MP, CO, BTN, SB, BB.
