The conundrum I had has been solved. The OW website wouldn't give the connection I wanted, so I hatched a plan to make it a surface sector and book a one way ticket separately, risk the connection and just rebook if I missed.

I then realised my flight was international to domestic and the connection time I was risking was a no hoper, with a border to contend with. had it been domestic to domestic I would of chanced it, so I've just got to leave earlier and endure longer layovers.
