How to Apply Edits to Several Features All At Once in JS API?

Hey Team!

 

So, long story short, I'm creating an application that allows users to adopt road segments as the OOTB Esri option won't work for our needs. I've got to the point where users can click on the app, a form gets created and populated, they can input the necessary information, and apply the edits. However, as it stands, users can only select one feature at a time, which won't work. 

 

I need users to be able to select multiple features on a map, fill out one form, and have the fields in the form be applied as unique edits to each of the selected features. The testing code block is below:
