Can I set a default parent folder?

I just purchased Hazel but in setting up rules I noticed a potential problem with my planned workflow.
Is it possible to set a default destination, or use a variable to specify one? I would like to have a folder for the year and within that have folders corresponding to various accounts. I have set up a number of rules to move incoming files accordingly. However, it appears that come January 1st I will need to go into each rule and change the destination to be under 2018 rather than under 2017. Is there some other way to handle this? Can I specify the <year> folder, or more generally, some arbitrary part of the path with a variable?
