Tiger Explorer Spare Fuel

I have the new Explorer after 3 years and many miles on the original. This new machine has come with the aluminium Triumph/GIVI luggage and I wonder if there is a frame to sit between the nearside pannier frame and the bike to strap a spare fuel can. There appears to be a fixing plate for something, but at the moment, it's just wasted space. Any comments anyone?

 

Thanks. I've head a look at these places and there's nothing specific. Triumph (of course) won't endorse or recommend anything unless it's 'approved' and even GIVI who make the cases for Triumph can't offer anything.
