D365 Sales Using Address Entity

Hi 

We have a requirement to use the OOB Address entity to capture around 1000 site address per Account record in D365 Sales.

These site details will then need to be associated to an Opportunity / Quote and Product line. So an Account could have an opportunity with 200 product lines all referencing different Sites.

Are there limitations to this approach as apposed to using Child Accounts to capture the Site addresses?
