Unfortunately, there is no option at the moment to simply tick to have the ID document image saves to the Salesforce record along with the completed signed document. The ID evidence data is stored on different servers for data privacy reasons.
When sending from Salesforce you are still able to get the ID image from the envelope record directly. However this would be a manual task to retrieve and upload it to Salesforce.
In order to automate the retrieval you should be able to use the DocuSign ID Evidence API, which all require some APEX coding to make the right API calls. I doubt that this functionality is already included in the DocuSign Apex Toolkit for DocuSign eSignature for Salesforce. Therefore, you need to make custom API calls from Salesforce.
