Approval Process for Social Media Posts (with Notifications)

Has anyone found a solution to this? We are coming from Sprout Social, which has customizable approval workflows and is extremely user friendly so we are needing some typer of solution for Hubspot. Anyone know if Sprout Social is able to integrate the content calendar? If we could do the whole appoval and calendar creation in Sprout, then export it and import it in to Hubspot, has anyone tried this? Or something similiar?
