Extra Research Levels?

Working on a mod. 

How do i add extra research levels to a technology?  Example.. i want to add 2 extra levels to Deep Core Metal Mining, want to bump it up to 4 levels instead of 2.

For larger multi star maps.. seems that we max out the tech tree halfway through the game.  I want to add some more depth, tech wise.

MaxNumResearchLevels #

Putting a 4 instead of the # should do it. The only problem is, the game might have the max number of levels be 2. I know this is true for other things, such as the number of levels for capital ship skills (they can be at most 3). If it doesn't let you do that, I would just make more research subjects, each with 2 levels.

Raising the MaxNumResearchLevels # will work. I maded techs with 10 and more levels without problem.

Just remember to change the "Prerequisites" entry's levels as well.
