It would be really useful to have a limit specific to the downloads report.
The current behaviour of the archiver will place all downloads under a top level row where the top row is the site hostname. Because of this, all the downloads are lumped together into a single subtable which by default will be set to 100 rows (https://matomo.org/faq/how-to/faq_54/):
And because this limit is shared with the Pages report, simply increasing the limit to 1000 or more could quite easily lead to performance issues when archiving.
