How I represent In Pacto flexible Cavalry and Infantry units of 2 elements

1 base of each of the types they can switch between in each TuG - e.g. the cavalry would be 1 base with 3 figures and 1 base with 2.

And infantry a 4 and a 3.

So you puts the fuller bae at the front for the denser formation.
