Version control in Azure Board

Hi there. 

We are evaluating Azure Boards for use as a requirements management system.  One feature that RMS often have is the ability to version individual requirements or work items.

So if I create a work item: "Requirement 1" and have it approved, I can create a new branch of that same item and call it "Requirement 1 - revised" which might sit as submitted for review before it is approved and replaces Requirement 1.  Therefore they are not different objects, just different instances of the same object. 

I can do this in Sharepoint lists and Confluence, but of course they are different types of tools.  To combine this with Boards' other features would be great.

Can anyone tell me whether Boards supports this and point me to a reference?

Let me know if not clear.

Many thanks!
