Download all translations

Hello, how can I download all WPMU plugins translations for a language ? I use 20 plugins

Now I need to open 20 pages from here https://premium.wpmudev.org/translate/projects
Then click my language on each of the 20 pages
Scroll to bottom on each of the 20 pages
Select .po on each of the 20 pages and download
Then select .mo on each of the 20 pages and download ...
