Moodle plugins directory: Mass Actions block | Moodle.org
Mass Actions block
This block allows instructors to perform actions upon multiple resources or activities, rather than having to perform repeated actions on individual items.
To use this block, Javascript must be enabled in your browse and you must be in editing mode in the course home page. The user must have capability "block/massaction:use". The block should work in most course formats.
Supported actions include mass selection, indentation, deletion, hiding, showing, making available, duplicating, and moving. To select items to perform actions on, simply click the checkbox next to the activity or resource or use select functionality from the block. Then click the action you would like to perform in the block.
If you encounter bugs or have suggestions for improvement, please use the bug tracker URL and I will work on those as quickly as possible.

But according to the profile page of lead maintainer Clem Smith, his last site access was already May 2018. Matthew, could you please make your version with the 3.9 fixes into an official plugin?
I don't know if any of those who have done updates would be minded to maintain it going forward, or how that transfer would happen if the current maintainer is uncommunicative.
