(help) Trying to use Rigify on a digitigrade Character

Okay, so what I’m basically trying to do is add an extra bone to the Leg armatures of the basic Bipedal Metarig provided by Rigify for a character that has digitigrade legs like in this image on the right.

But i cant add to it or sub divide it, I’ve tried looking up solutions but I’m probably not wording it right to find what I need.

Any help would be appreciated.

Thanks for reading,

Maseo

the thing under your name at the bottom does not show up. I rig my own characters so I don’t really know. What I do know is that you can’t subdivide a bone (as of my knowledge so far). You might want to delete the bone entirely and just segment it out
