Selling from Blockchain: IBAN reference number?

I’m trying to sell bitcoin on blockchain to swift/IBAN however it doesn’t appear to allow me to put into the unique reference identifier.

Anyone have experience selling from blockchain to Revolut? Am I maybe just missing something?

Hi there. At the moment you can buy, sell & transfer within Revolut! However, we’re looking into the possibility. Please note, we’ve communicated this long before we launched this feature bit.ly/2wUvxvZ
