How do you push leads that were added to Marketing Hub to ZCRM?

Hello,

Seems like a silly/simply questions but the sync seems to be specifically for importing leads from the CRM into Marketing Hub. If I add or collect leads directly on marketing hub, how do you send/sync these leads over to CRM without having to use webhooks or API calls?

Thank you
