Computer analysis suggestion

As we all know

? is a bad move

?? is a blunder

?! is a dubious move (inaccuracie)

This is what the computer analysis tells us. Why can't the computer also give us the

! good move

!! Phenominal move

!? Interesting move

I want to see them on the analysis as well so I can see where I made my good moves.

because the computer doesn't see which moves are amazing to humans

It may be too confusing to have more than the standard symbols 

if you think about it, any move that does not have a ? or ?! next to it in a computer analysis, the computer thinks it's a good move. So that would result in a sample following:

1. e4! e5 2. nf3! nc6 3. bc4! 

etc. 

also, with the phenomenal moves, think about how much code it would take to define every aspect of a phenomenal move. It also depends on what the person who's doing the coding defines a phenomenal move as.
