Obviously, the current setup of collection only of these chemicals is not ideal.
BUT, as Wayne has said, this is a new licence and hopefully this can be ironed out or made a lot easier for both suppliers and buyers.
If Wayne is meeting with the HO, he will be able to air these concerns.
As for suggestions, I take it that facetime holding your licence and ID or similar pic sent to supplier would be no good? And then post the licence to the supplier to fill in and send back with the order. Obviously only sending to the name and address on the licence.
