Make it Possible to Cancel Nitro Boosts

The title is self explanatory, but I'll also add a personal story: 

I have had Nitro for almost two years now.
I boosted a server earlier today, but regretted it a while later.
I do not wish to boost ANY server, at the moment;
meaning, I don't wanna 'transfer' the boost.
Though, I cannot 'unsubscribe' either, since it's included within my Nitro plan.

Why can't I just simply cancel the boost?
There shouldn't be a week-long cool-down to that, too.
That's kind of idiotic.
