Overwrite DefaultLayout in environments.xml.cfm

Is there a way to overwrite the DefaultLayout in the

I tried the following but no luck.

<Setting name="Layouts" value="{'DefaultLayout':
'layout.main.v3.cfm'" />

Forget it I figured it out .........

This is how you do the default layout
<Setting name="DefaultLayout" value="yourFile.cfm" />

This is how you do a folder layout
<Setting name="FolderLayouts.theFolderValue" value="yourFile.cfm" />

And like they say in the docs just do a dump on the follwing and you
will see how you can override.
