How to export 24h+ streams to YouTube? Highlights storage is full for me

Has anyone found a workaround for this? I know YouTube's limit is 15h or something like that(?) so I'm stuck when it comes to trying to upload these. 15m parts would be kind of ridiculous and there's no way for me to split each VOD into bigger highlights since I don't have any storage. One way I'm thinking about doing it is backing up every short highlight and deleting those to get enough space to split up the longer ones but that'd be a last option, if I can avoid it I'd like to.
