Adding a research subject to TECH

The Phase race has a research subject called "RESEARCHSUBJECT_POPULATIONGROWTHRATE" I would like to have that appear in the TECH  window in the civilian-policy box.

So I copy that file and renamed it "RESEARCHSUBJECT_POPULATIONGROWTHRATETECH" Then I change the rest of the new file to...

TXT
entityType "ResearchSubject"
hudIcon "HUDICON_RESEARCHSUBJECT_POPULATIONGROWTHRATETECH"
smallHudIcon "HUDICON_RESEARCHSUBJECT_POPULATIONGROWTHRATETECH"
infoCardIcon ""

Then I go to the String file and copy the ID strings from the phase and rename them tech, I also remember to edit the number of strings at the top accordingly. But thats as far as I can remember, I did this when sins first came out but that was long ago. Any modders out there want to tell me what all files need to be modded for that to happen would greatly appreciate it.

Using the existing hud icons and graphics for the phase are fine I dont want to mess with that.
