Anti Virus Schedule Weekly or Monthly
Add an option to scan (besides daily at certain time) weekly of monthly. Some scans on large drives take a whole day and don't need to be scanned weekly but rather 2 weekly or monthly.
Almost all antivirus having this Features & i surprised that it is not in Sophos,
this should be easy to implement because Windows Task Scheduler is used for this. And this has options to set multiple run-times.

Configure Scheduled Scans to add functionality not to scan every week but with a pattern of 2/3/4 weeks or every 1. Tuesday in the month.
Also it should be possible to configure targets of scanning (like single paths and/or specific devices).
Last (but not least) there should be an option that a computer inactive at scanning time should be enabled to catch it up after activation.
