I use the confluence macros to setup several queries in a single confluence page. All the queries are related to a specific Account because I'm using this to create an account plan.
In all the queries on the page I'm restricting the data by accounts. It would be nice if I didn't have to go to 10 different queries to set the account ID. I could create a template and then just go in and set a page variable called account ID and then setup each of my macros to use that variable. This would allow me to create a new account page in just seconds.
