Do sub accounts let me connect to multiple go high level integrated agencies? Right now I have the pro plan and my Go High Level integration only allows me to connect to one sub account, so for real time booking I can only book to one calendar in one sub account, while I want to have access to calendars in different Go High Level subaccounts. So, do I need to upgrade to the Growth Plan for these capabilities or do I have to make a new workspace for each agency that I want to work with?
