shared way marker with allies in wars

[native spoke]

I always end up fighting enemys alone especially in holy wars and I loose it because my allies refuse to help me, even tho we had much more men and the advantage. Why can't I place a stratetic way point or marker so the AI doesn't splitt up so we can attack togheter?

Edit: A feature like mount & blade had where allied troops can follow you.

I often found the reverse issue : the AI will abandon a siege that is almost over just to bring their million men in a fight that only requires half of it. They really should be able to detach besiegers.

I mean tbf it is historically accurate for the different rulers in a crusade to lose due to them being uncoordinated
