Hi Jack,
That isn't possible right now. There's an issue dealing with adding that to the 1.3 consumer codebase - see MDL-69275. That issue deals with adding support for submission review launches, as described here: https://www.imsglobal.org/spec/lti-sr/v1p0 (login required). That reference to the GradebookResultMessage spec in the AGS2 spec should actually be to the submission review spec - see this forum post - http://www.imsproject.org/forum/learning-tools-interoperability-public-forum/197391. it seems IMS didn't update that spec as they said they would.
Given you're dealing with a launch from Canvas, however, I suspect you're in need of support for this in the Moodle provider code. Unfortunately, we're in the same situation there in that it's an unsupported spec right now. In fact, 1.3 is unsupported right now (coming in 4.0). I think the submission review workflow is something to consider for the future however, so if you create an issue on the tracker, I'd be happy to triage it accordingly.
Cheers,
Jake
