Package Setting for digital lending

Hi, we create a package through REST call(https://sandbox.esignlive.com/api/packages) and upload the files to them incrementally with separate REST calls(https://sandbox.esignlive.com/api/packages/{packageId}/documents). Here are my questions: - For passing the registry data, are we limited to pass that on the creation of the package or can we update the package info with that while the package is still in DRAFT? - is it possible to pass the registry data when doing the rest call to upload the document? https://sandbox.esignlive.com/api/packages/{packageId}/documents Thanks, Sara
