Merge Rules from 2 Computers

Hi There, l hope someone can please help. I am running Hazel 4.09 on my iMac and my MacBook Pro. ALL rules monitor Dropbox Folders, but 90% of my rules exist and were created on my iMac.
Since l seem to be using my MacBook more now i would like to sync my Folder Rules via Dropbox on both computers so that if l want to create a new rule it doesn't matter which device l am using. HOWEVER i have a number of complex rules (well they are for me..!) on my MacBook and obviously don't want to lose them. How can l get all my rules into one Hazel Box, and is it even possible!.
I also want to confirm that Hazel service won't "Fight" over who saw the file appear in the Dropbox folder first.
Sorry l am new at this but am keen to really start making the most of this great service in an attempt to achieve an "organised" paperless office.
Thanks in anticipation.
