How can I auto select the image path ina TV

Dear All,

Some week ago I create a modx web site with 2.15 version
I also create a Teplate Variable for images.
I could enter a path to the default images folder due to the field "base path", the 'option entry' tab. It very useful because the path is auto selected for customer and when we look for images, it automaticaly open the right folder.

Now I am creating a new MODx web site but with the version 2.2.0.
I also create a Template Variable for images. But this time I do not see that option.

Do you know how can I do it?
In a Tv of the 2.2.0 version, there is the field "Defualt Value". This allow me the display the path to the image folder, but it does not open the right location when we look for images.

Thank a lot

2.2 introduces Media Sources. Go to Tools -> Media Sources. Works great.
