Siebel Loyalty Member (1:M) accounts

Hi All,

 We are working on Siebel 8.1.1.9 Loyalty Member configuration , we have a typical Account setup where in a parent account has multiple Child Accounts (1 Parent can hv 10 Child accounts) and each Account can buy some products, We would like to have a member created with Parent account but all the purchases done by child should also credit points to the member to which these accounts are childern.

  1 Loyalty Member should be able to cater to multiple accounts and all these accounts transactions should collectively provide points to the Loyalty member. Now the question is how can we create a loyalty member to deal with these group accounts and how do we consider transactions.
