If you want to create leads/contacts/targets from a webform, you can use Suite’s own generator for that:
Otherwise (since other modules are imho not supported by that feature), you can still create your very own form and submit the information via Suites rest api to the CRM. This is a bit more programming, but you can create each desired record as you wish.
