On behalf of a customer, received as KB article feedback:
"Having set the date range to a particular set of values (3 months or custom), it woud be good, convenient, efficient and useful if that date range was also an option when preparing (previewing, printing or exporting) reports that are related to VAT Returns. Or any other reports for that matter.
Use the VAT Date range could be a shortcut available, in addition to setting the date range manually using the calendars.
This is something I would request Sage consider for a future update."
