It would quite useful for users to be able to run a script or a console command to automatically create a crontab for the core:archive task.
This would preferably be an interactive command where the user can input specific values or continue with defaults.
For example the user could maybe choose the following:
Some more advanced options that can maybe also be set at the same time that the core:archive is being created (As a prompt perhaps) would be the time before the different reports (Day, week, month, year, range) are considered outdated with some defaults and recommendations for better performance.
crontab -l | command_that_adds_a_line_in_the_end |crontab - might work on a large amount of setups and doesn't need root access (of course then it is a user crontab and doesn't need the www-data column).
