Sandbox connector for Netsuite (suiteSync SCN)

We have a Netsuite integration in legacy test mode that uses the netsuite connector (suiteSync) to connect to our Netsuite sandbox. I was told the suiteSync connector owned by stripe does not currently support the new sandbox configuration. Is there a plan to add support for the suiteSync connector to sandboxes? If so is there a timeline?
