Hi Marko,

This functionality is now in place. You can show up to 50 students on a page, select as many as you want and enroll them with one click. If you want to move to the next page to select more, the system will ask if you want to enroll those already selected before proceeding. If you click yes they will be enrolled as you move to the next page.
I will merge your idea with the same one.

Thank you for your feedback, Marko. We will look into this.
