Ship to Site from Other Business Unit

We have a use case where Customer from USA BU will buy a subscription product and ship this to a site tagged to Asia BU. Now, we have to create the subscription is USA BU as the Customer and Bill to are from US. But we also need to capture the Ship to in subscription product level, which is from Asia BU.

We are unable to find the customer sites belonging to other BU in subscription product. Is there any setup which we need to enable so that we can see customers from other BU?
