Small Suggestion: Resource-Only Toggle for Harvesting/Collection

This is my first time setting up my town for one of the thousand events that require Construction Points. Its...a little tricky. And I play on mobile so...this is kind of nerve-grating.

I was thinking... Is it possible to create a toggleable switch that would prevent you from collecting/triggering any of the Building Level-up crates floating above the buildings? This would mean that I can freely collect a buildings completed production without having to play minefield.

I mean...I would pay for this option, ($10?)

An alternative would be that instead of the production crate appearing above the building, if you enter the building there will be a button to confirm that you want to proceed with the level-up. Or, vice-versa, it can be the buildings produce completion button on the inside and the building level-up crate on the outside. Or both on the inside and outside...though I'd prefer the last one to prevent accidentally brushing up against it.
