Would be cool to have the ability to put a dynamic variable in the file name of the report that gets delivered via email. For example, if I have a daily report for open items, rather than being delivered with the same file name each day, it would have today's date appended to the report name as the file name.
Would be great to also have this option within batch jobs, to give each report a unique name, like being able to append the filters applied to the file name. For example, if I create a batch job to run a store report for each store, the store name can be part of the file name.
