Hi,
Thanks for your message. We understand what you’re looking for, but unfortunately for the moment the system is unable to capture a digital signature, I’m sorry. This is a feature we may introduce with the next major releases of the plugin, but the signature collection will probably be on a step after the rental order confirmation, just like how right now the system allows customers to upload their IDs, licenses and documents once the rental order has been confirmed, either manually or after a successful transaction.
If you wish to implement a similar feature for the moment we can suggest creating an override for the page (View) that allows to upload documents. Thanks to the Overrides Manager tool in the Configuration page you can work on a copy of the original template file that generates a specific page, so that by installing future updates your changes and customization will never go lost.
We hope this helps!
