MSP and Enterprise License (To define pools from which license file)

I have 2 licenses,one of which is using for 1 customer and other license is shared among n number of customers (MSP - Multitenant).Say for an example 1.License for Customer A (200GB) expiry date : 2018 2.For other n number of customers (500 GB-50 GB per customer) expiry date 2019 I can define pools for each customers. My question is,if I am stacking the above 2 licenses in one license master,can I create a single pool for Customer "A" which should uses the first license file and not to share it with other customers.Is that possible? Please suggest how can I achieve this kind of deployment. Regards, Ansif
