Templates for species rights (Do I need to do those chores?)

[Mermel]

I have the following prolem.
I like to play xenophobe human bigots that like to enslave or outright purge every non-human species in their empire.
Now, when I conquer some other worlds lately it happens that they have literally dozens of different species on them.
And what I need to do then is to select every single species and change their species rights so they receive a proper purging.
Generally that is the point when I quit my session.

So, does anyone know something about a mod or feature I'm missing, that lets me easily change a lot of species rights at once?

 

[Astelon]

Change the default species rights.

 

[Mermel]

Change the default species rights.

And there the feature is.
Not as powerful as I hoped, but definitely good enough.

Thank you
