Taxing a new vehicle now without paying for the whole month of November

As above, is there a way I can tax a new vehicle now without having to lose out on a months worth of tax?
I've recently bought a converted van into a horsebox, and I want to collect it on Sunday, however I will have to pay for the whole month of November in tax when I'll only have had it for 2 days this month if I want to collect it then
Is there any way to avoid this?
