Bookmarking a Recurring Report

Every month I do some reports and export the data into a spreadsheet. I’ve noticed that the URLs for the generating reports use fixed date ranges. For example, if I generate a report (say in mid November) for “Last Month”, then the URL contains the date range of Oct 1st through Oct 31st. This means that if I bookmark the report page and revisit the report (a month later), the report page will always have data for the month of Oct. What I’d prefer is if the URL used a parameter like “last-month” instead of a fixed date range, so that I could generate a new report every month by visiting the same, bookmarked page.
