Basically, I think having the ability to assign templates to groups of planets and then adjust that specific template through the planetary govern function would be so, so, so helpful.

You could then have 3 or 4 or however many templates running on as many planets as you want and instead of having to adjust the govern budget screen for each one, or hit them all with the exact same plan you could tailor them to roles and levels of development and cover your empire far more quickly.
