Change Y value calculation when autoLayout = true

[desenvolvedor-apanheidoexcel]

Where the value of x,y is calculated when autoLayout = true?
I need to create a level attribute, which forces the value of y, but I want to keep the x calculated by autoLayout.

I thought about changing at the point that the x,y position is calculated automatically. It would read an attribute and change the value of Y setting to value of attribute.
Am I right?

Where can I change the code? I using gs-ui-android and gs-core
