Description of problem: At present Express has the daily,hourly,minutely,monthly and weekly directories under cron/ README says that scripts in these directories are executed by run-parts. It is not possible to execute a job at say 4:30 every Monday. or every 45 minutes, etc. Allowing crontab files in the cron cartridge will make it much more flexible.
Changing severity to low since this is an enhancement.
As much as I'd like this feature, I'm Closing as WONTFIX. We're evaluating some different infrastructure for more customized scheduled jobs. Unfortunately there are a number of issues with cron running as multiple users (it was designed to run as root). As such we're having to look elsewhere for a proper scheduler.
