Properties such as lifecycle stage or buyer persona have unique characteristics that are not replicable so far in hubspot. It´s necessary that when new business units are created, these native properties are created for each of them.
For example, funnel reports are only possible with the lifecycle stage property or with the pipeline. If we use the same property for two business units, a contact that is already a customer of one business unit and qualifies as a lead for another business unit will not be visible in the second funnel report.
