Auto buy supporting structures

A toggle button on the investments page that when activated will automatically buy all the required low tier buildings when you click to purchase a higher tier. It would be even better if when this button was toggled the price on the higher tier buildings changed to reflect the added cost. So the price to purchase one of the tier one buildings would not change and clicking it would just buy the building. The price on the tier two building would show the amount needed to buy both the tier one buildings required to unlock that tier two and the cost of the tier two combined. Clicking that button would purchase both the necessary tier one buildings and then the tier two building.

This way when you have some decent money you could just click on the actual building you wanted to buy instead of trying to manually figure out how many tier one buildings you would need and working up from there.
