Drag & Drop URLs to Objects

I think it would be incredibly useful if there was the ability to drag and drop a link (URL) onto an object and have it automatically append as a weblink at the bottom of a selected blocks or text property without having to open a page/object; or, as an alternative, a special weblinks property that enables this functionality for a given object type.

An example for how this works in practice is Trello. If you drag and drop a link (using the icon to the left of the URL in a browser) to a card on Trello, it automatically attaches that link in the "links" section of that card.

This would greatly speed up workflows where you want to keep track of sources, references, etc. related to a given object.

As a bonus, it would also be great if you could drag links/urls directly into the weblinks page to create weblinks; as well as directly into blocks and text properties to create weblinks (similar to how you can drag in images into a text blocks property).
