I was wondering if there is a way to have the dates of "available from" and "until then" show up on the line with the assignment name on the module list? The due date shows up and the points show up on with the name of the assignment on the module list. It just would be nice to also see the dates of availability from and until on the same line instead of having to open the assignment and edit it.
No, it's not possible from Modules, but have you tried using the bulk Edit Assignment Dates feature? It's a fairly new feature but a good one if enabled in your instance of Canvas. Try this:
This page should show you all of your Assignments and give you the ability to add or change dates from a single page. You can even filter the list by date to get a smaller subset to view.
More information about the feature can be found here
