How can I mod my game so my Polish king and heirs are in groups of Retainers instead of royal knights?

It is tricky, but rather easy. Still you must either give them different units for early and late era or extend Retainers use. I would rather do the second + add some royal Polish knights for late since Retainers were numerous only in High and early Late eras.

Do you have any modding experience ?

If you want I can help you - send me a PM if you want. ~;)
