Feature request: Allow instructors to copy an existing group

We have several requests from instructors who use similar (relatively large) groups for multiple assignments, with only one or two members being changed from assignment to assignment. They'd like a way to copy their existing groups so they don't have to recreate the groups from scratch each time.

I imagine this would be done with a new column in the groups table to Copy Group, where each row would have a Copy link. Upon clicking it, a new row would be inserted in the table with the group name having a " - Copy #" appended on it, similar to how Samigo and Assignments append a Copy # on the end of copied items.

Note: "Copy" links need to be properly associated to group name for screen reader accessibility.

Recommended naming example to match Samigo/Assignments (copying a group named Group 1)

• The name of the first copy would be Group 1 - Copy #1.

• Copy the original Group 1 again without changing the name of the first copy, and the second copy would be Group 1 - Copy #2.

• If you copy a copy without changing the copy's name, another Copy # would append, e.g., Group 1 - Copy #2 - Copy #1
