Is there a way to commit the availability evenly using fulfillment management?

HI,

I am trying to using fulfillment management to distribute the available quantity to customers.

Below are the scenarios,

Scenario 1:

Customer A Customer B Customer C

Item 123

Availability 500

Customer A orders for 50 qty, Customer B orders for 60 qty & customer C orders for 70 qty.

Whatever may be the quantity ordered, customer A should get only 5 qty, Customer B should get only 6 qty & customer C should get only 7 qty.

Scenario 2:

Customer A Customer B Customer C

Item 123

Availability 100

Customer A,B,C orders each 100 quantity

Whatever may be the ordered quantity each should get even value like Customer A = 10 qty, B = 10 qty & C= 10 qty.
