Please be more specific. For what items do you want to be able to provide custom labels? How do you imagine this would work? What if the document you are using moves to a different location?

Custom labels are useful for certain elements, such as edit boxes, combo boxes, check boxes, radio buttons, textual and graphical links that either don't have labels or are labeled poorly on specific web pages, Microsoft Word documents, and Adobe Reader PDF documents.

Closing as duplicate of #5874. While this issue is broader in scope, #5874 has pull requests associated. Furthermore, the need for custom labels in Word en PDF documents isn't clear to me.
