Improvement: Selection of the enrollment method during import

[stdoma]

Hello!
Currently the admin defines in which enrollment method users are added when the function is used in the course.
I would like it if the admin could define that the enrollment method can be selected in the course itself.
The selection of methods in the course should then match the available/configured methods.

In the course, the enrolments can be used, for example, to separate users historically.
For example, you can deactivate the self-enrollment of new users in one method and add a second self-enrollment to the course.
In this configuration, pre-selection via the admin is a bit of a hindrance.
