How to store the address the asset lives at.

[androolloyd]

When we're creating a new subscription the wallet address could live in the meta data that is generated along with external ID, there should be a use case where you can have multiple assets stored in multiple addresses and have those address all approve the ERC-948 contract to manage those assets inside a subscription.

Currently the address is stored in the struct of the subscription.
