More Spending options with gems...

The way I see it, if I spend money on gems the only option I have is to finish builders, fill storages, yada yada yada. The point is I feel like there needs to be more options with my gems. What about being able to boost builders? Or how about we are able to put a certain amount of gems into something that is taking awhile to upgrade to make it take less time. IE: 7d till Wizard tower 7 right. If I were to start that it would give me a set amount of gems to complete it for those days as it counts the days down the gems go down. Lets cut to the chase if I only have 100 gems and it take lets say 700 (not the real amount for this amount of days just an example.) to completed the tower and I put in just the 100 I have it takes a day off. Understand what im getting at?

7d for wizard tower 7=700 gems (100 gems per day for the sake of this example)
700 gems-100 gems (100 gems coming from what the player has) now equals 6d till completion.
If this would be to difficult to add maybe just add in being able to gem builders for a certain amount of time. 15 gems for two hours at 4x the speed.

Let me know what you guys think...

Boosting builders is ruled out because if you boost the building and gem it it would take 1/4 the gems normally but I like the other idea. Of an upgrade takes six days and I have thirty gems, why cant I just put those into it?

You could just wait 6 days, then when the gems r low enough, put the gems in to finish the upgrade, y waste supercell's time writing the code for this. the builder boost is ruled out. Also this thread doesnt give more uses for gems. Just saying I expected a new idea with gems.

The first idea has been suggested a ton, and the second would hurt Supercell's profits a large amount.
