Lastest build files url

Hello there, 

I was wondering why it isn't possible to simply use a placeholder like 'lastest' or 'newest' to access files, because it makes it very easy to connect external services to it, so that you have an always up to date url, without having to make another additional request to the api first.

Example: ''http://mygithost/user/repo/build/lastest/workspace/file1.txt''

Greetings
