There you go. As a bonus i also made all units that benefit from recycler upgrades have all of them at the same time. So your Marauders for example can have Hover engines, rocket pods and ERA armor all at the same time as seen in the screenshot.
Note: It only works with 1.87 Public beta 2, The current one. And you can't use this in online games as it will cause mismatch error.
