Is there any way to reprocess a specific Custom report?
Having more than 200 million visits a year it would be most convenient to reprocess specific reports instead of all reports. 
Hi @h_perfect ,
Yes, it is possible to process a specific Custom report from the console.
./console/customreports:archive [--idsites="..."] [--date="..."] [--idreport="..."] [--disable-segments] [--periods="..."]
–idsites The ids of the sites you want to archive custom reports for (default: “all”)
–date The date or date range you want to archive custom reports for
–idreport If set, only a specific report will be archived
–disable-segments Disables archiving of pre-archived segments
–periods Specify which periods should be archived. A comma separated list will archive multiple periods (default: “all”)
Wonderful, thanks! 
Altough I need someone in my matomo-team to run the right commands in the access the console, that is exactly what I wanted to hear.
