MathType help: how to align equations separately?

Hi all, I have a simple question.

In MathType one can use the option in the menu: "Format -> Align at =" to align equations at the '=' sign. The problem is that MathType aligns everything in the current window and not just what you selected.

Ex if you have this in your window:

Code:

`f(x)=2x+3`

g(f(h(x)))=4x

2y+3x=4

x+y=2

it becomes

Code:

` f(x)=2x+3`

g(f(h(x)))=4x

2y+3x=4

x+y=2

I want to align only the last two equations so that the functions are still left aligned like this:

Code:

`f(x)=2x+3`

g(f(h(x)))=4x

2y+3x=4

x+y=2

How do I do this? Intuitively I tried selecting only the last two equations and then using "Align at =" but MathType still aligns everything.
