Refresh Media Tiles only during scheduled periods to save bandwidth

So I followed Rob's guide to get my commute time in action tiles and it works perfectly. However, as many others pointed out this can cost a bit of money due to Google charging per 1,000 requests. 

Here is my issue: When I wake up in the morning I want my commute time to be updated when I am about to go to work. So if I set this up on my "commute tile" and my wife's and let it run all day at a 1 minute refresh rate, this could become very expensive, very quickly. (about $5 every 8 hours at a 1 minute refresh rate). 

My solution: What if we could limit the time of the requests on media tiles or set a time to request? For example, I wake up for work at 7 and leave at 7:30 on the weekdays. So I would update my drive time at 7:20 and 7:30.
