"You can use an emergency travel document to travel to your destination through a maximum of 5 countries. You can also normally use it to return to the country you’re applying from if you live there.
"Your travel plans (countries and dates) will be printed on your emergency travel document. If you change your travel plans once you have your emergency travel document, you’ll need to apply for a new one."

I think this sounds like the Consulate will sort you out.
