Wave save slots and save slots for settings towers/road

Hello. Sorry if my english is bad but i hope all of you will understand my idea.

 

What you think about option to save your wave settings?? Maybe to save all waves in one time or for all waves individually…Or i think the best this both option… I always change my waves setting and sometimes when i change something in waves setting, sometimes is hard to back to your previous settings… And this same too towers and road… What is yours opinion??

Very good idea, was suggested and discussed before.
