Dealing with sub-folders

I'm relatively new to Hazel so forgive me if the answer is obvious......
I have a root folder which contains several sub-folders and even a few sub-sub-folders. OK I can set Hazel to monitor a sub-folder but is it possible to monitor the root folder such that any modification in any of the sub-folders creates an action? In this case it would be to copy the whole of the root folder including sub-folders.
As work goes on it may lead to a change in any of the sub folders, so unless I create rules for each sub folder and any others in the folder tree something could go unrecognised
Basically, is it possible to create a single rule for the root folder which looks for changes anywhere in the folder tree and then copies the whole of the root folder to another destination?
