I'm mainly looking for a way to simply make an upgrade affect a unit it normally doesn't, is there anyway to do this?

EDIT: I found out on my own in only a few minutes after posting this, You go into the upgrade's data table, by easily clicking on a unit it affects normally and scrolling to it's upgrades, clicking on the upgrade and looking out of the lower left box to the large right one.
You look for the "Affected Units Array" Option or something which lists more than 1 unit (usually).
All you do is simply add the unit you want to add, which could be with the shields upgrades in this case. The unit will have the name in the list that it will have ingame.
