It is awesome that we can generate reports for spaces in order to manage it and see storage and last activity.

Currently, Last Activity is limited to displaying results for the last 12 months, and it would be useful to have an extended time period to bring the information as some spaces could be idle for more time. It would be useful to have this information to audit the spaces in the site.

Results are currently "blank" in the last activity column for periods greater than 12 months.
While the period is not greater than 12 months, it would be useful to have a message in the report mentioning it, so users don't think it could be a bug in the report.
