Why not upload it on the donut? Make a separate account for DDR and try uploading all versions. Maybe in this case the 100MB size limit shouldn't be taken into account and just make a 700 MB LOCAL instead. Since you're an admin. I see no problem why you shouldn't do this except maybe you're not the one that can configure the limit in the first place.
I'm not too familiar with the donut's possibilities, just making a suggestion here.
