Hey Kristin - consider turning this problem on its head. Instead of developing a template report, create a project report that focuses on the templates used or applied. Does your organization typically apply more than one template to a project?
If not, then you could create a project report with the entry date column sorted in descending order and grouped by template>>name. You could then isolate the last time each template was used if this is a one-time activity. Same deal with template(s) used where you can add a filter to only show entry date in the past week or so and then create a chart to show how many projects used that template in the last couple of days.
