AutoCAD :: Setup METRIC Project That Uses Meters Instead Of Millimeters

I am trying to set up a METRIC project (that I want to make template) that uses meters instead of millimeters.

So I created a new project, without the use of any template. I copied from the default Autocad templates folder the Model and Sheet templates to the new project folder and I set the units, scale and grid to meters and changed the path in project properties to these files.

Everything seems to work fine, except creations of sections/elevations. 

I edited the SectionStyles (Metric).dwg file in default styles folder and It works fine.

But I donțt want to change that file in the default folder, but to change the path of the section styles in the project. The only way I could do that was to change it in the tool palette - right click on callout. 

So how can I make the SectionStyles to load from a specific location for a project without having to right click on every callout that I want to use and change it manually?

There are some other things to do/change for making the project template that I want? (I am referring to the units setup).
