User Group Enrolments in LMS Course

I have many courses in my LMS website for my internal users of my organisation.
The courses i have created with self enrol that users can enrol themselves.

But I have some courses about master Management and other admin related transactions which I have restricted self enrol.

I have created user group of Admin and IT department which will have the course access.

but when I see the course enrolment it does not have any option to enrol user groups
I have more than 50 members for that courses and like 20 courses so enrolling members one by one is a very time consuming task.

Is there any way to enrol the user group to the particular courses that will be very useful.

I guess you can create a user batch and the add the course to that batch
