When baking a mocap biped 3 as an agent, I notice that 4 bones are automatically selected in that one window

LeftFoot_To_LeftToeBase
LeftToeBase_To_LeftToeBaseEnd
RightFoot_To_RightToeBase
RightToeBase_To_RightToeBaseEnd

So I'd like the same function when baking my own character. Renaming the bones to those names is not doing the trick.

Any tips ?
