Free vehicle choice (user request)

By MarkC9: Is it possible to get an update that allows us to choose which vehicle the undertaker uses?

Basically a few friends and I create custom coop missions in free-roam. It would be nice to have a "cleaner" to call to get rid of certain dead bodies. Of course being gang warfare, the cleaner would likely come in a truck, not a hearse :D.

If you got the time, would be great. Thanks.
