Can TFS Work Item Icons be Changed?

How can you change the icon that represents a work item type in TFS Web Access? For instance, a bug appea开发者_开发问答rs as a page with a red squiggly line, while a task is a page with a red check mark. These look a bit too similar to us, and we'd like to differentiate them with different colored icons. I suppose we could replace the image on the TFS server with another, but what if you only wanted to replace these in a single team project?

It is possible to change the colours of the icon by updating the <WorkItemColors> configuration, as described in this answer:

The link is for TFS/Azure Dev Ops 2019, but does work for earlier versions.

The result is something like this:

You can upgrade to TFS2010 which uses two completely different icons for bugs and tasks, but if that is not an option I would definitely go with just changing the gifs on the server.
