@laurenhenderso1 ...
There is a software application called Respondus that allows you to batch upload quiz questions from a file (the file has to follow a certain format). It's been a couple years since I've used it so, I don't know if something newer has been developed or not, but I'll provide you with a link to the blog entry I wrote here in the Community just in case:
Batch Uploading Quiz Questions with Respondus
I hope this will help in some way.
