War prep time

Hey,
While talking with a few of my friends, we came up with the idea of flexible war prep time. Since the newest update, the time has been decreased to 23 hours, rather than the previous 24. Upon seeing this, we were slightly confused as to why the change, and pleased with its results. That got us thinking. Imagine if the prep time was flexible. You would be able to set the prep time preferred while choosing the people you will include in the war. While trying to match your clan with another, the system could try and match you with someone within only a small distance of your preferred time and make the prep this the median of the two times. Yes, there are clearly some loopholes with this idea, but Supercell, if interested, could probably find ways to fix them.
Thank you for your time
