Redmine

We use the Bestest Punch Clock for Redmine plugin to track how much we work. We usually include a category and a comment, but usually omit the issue. We don't necessarily like estimating issue times and logging time spent on a specific issue. We would prefer to view the Roadmap progress bar as issues closed / total issues. In the admin settings under Issue tracking, could we make it an option to not have estimate times on issues and to not use time in roadmap percent calculations?
