Hello All,
Hope all you are good
in our current crm we have Account hierarchy like one account has multiple child and we have three types of account like 1.main,2.sub main and 3.sub
so in that our hierarchy like this:- "main" is a parent of "sub main" and "sub main" is parent of "sub" accounts
now we have new requirement from client that
"sub main" account has parent more than one
proposed hierarchy :

Note:in that on "Sub main" account there are n no of "Main" account, "Sub main" has more than one parent.
so how can we achieve this??it's possible in OOB crm or should we create custom?
i have searched many post for it but didn't get the accurate answer.
Thanks & Regards
Yash
