Hi Justin,
Sure, I think the feature request for Stock transfer between sites/contract brewers/offsite packagers on delivery schedule (Stock Movement Documents) - #10 by luke would cover what you are looking for. It would be great if you have any specific requirements for the feature; if you could add your comments to that request, that would be great. If I have misunderstood, please get back to me, but hopefully, that feature request is what you are looking for.
