E-Jet Advanced Range (AR) variants

I know that we have the E-195AR variant in AE, but what about the other AR variants, such as the:

E-170AR

E-175AR

E-190AR

Near the bottom of each page, there are a lot of PDF files to explore, including one that specifically outlines performance data comparing all variants of a certain type of E-Jet, such as the STD vs. the LR vs. the AR.

Is there any reason why we have not added these variants but we've added the E-195AR? Maybe because it was overlooked?
