autostart on a certain workspace

To autostart applications on a certain workspace would be a very handy feature. Would save a lot of time and nerves.

Every time I start my PC I open Internet, Mail and File Manager and then push Mail to the second workspace and File Manager to the third workspace. It's annoying.
I'm aware that there is third party software that might help but I'd rather have it as a autostart feature because I'm convinced that it affects many users as soon as you work with autostart and you have several workspaces.
