Extend Boost By 1 Hour Increments - Thoughts?

I love the new flexibility in the 1 hr vs 2 hr army boosts, however I'm now finding that my 1 hour boost runs out at inopportune times, either while nexting/battling or while I have my phone down while a big war army cooks. I'd love if instead of buying 1 hour of boost, then waiting for the boost to run out to buy more - if you could just buy an extra hour when you wanted to extend the boost another hour.

It would keep the armies cooking more fluidly and let me play more on my own schedule.

Not 100% necessary, but it would make things a little more convenient for some players and would probably net SC a few extra gems as well.
