Bonus breakthrough techs via modding a mission sponsor adds the required map icons. I used 50, 50 which seems to work exactly right.
I'd prefer to have the Commander Profile do this kind of thing, but alas, this is not an option.
Keep in mind that all this does is grant the ability to unlock the breakthrough techs, and some remain hidden via requiring deep scanning surveys. They get very, very expensive very fast. The last 40 or so cost about 80k research apiece, before any other bonuses or modifiers. I recommend sending out explorer drones with the tricked-out RC drones (with the perpetually full battery) to keep them charged up. 2 of each lets you gobble up the unlocks quickly. Depending on the map you may need to build a few tunnels to get to them.
