A randomization scheme is not complete without treatment arms. Treatment arms can be added to each scheme and can be assigned an allocation. If you have two treatment arms, and wish for 1/3 of your participants to go into Treatment Arm A, and the remaining 2/3 to go into Treatment Arm B, then you can set the allocation of Treatment Arm A to 1, and the allocation for Treatment Arm B to 2.

If you have multiple treatment arms, and want an even distribution among all arms, then you can set the allocation of each arm to 1.
