[Modules] Multiple Assign To Settings / Options

[culleng]

Problem statement:

There is no +Add option for multiple Assign To sections/people for Modules. You can only Assign To one option.

Proposed solution:

Add the option to "Assign To" multiple people/sections to open with different dates/times. The "WHY" is because when we cross-list sections into one course site, we want to open the modules at different times for different sections that meet at different times.
