Custom configuration and file extension

Hi, I'v made custom configuration for my file extension (for example extension is *.rqs). I can't find appropriate settings for automaticaly activating/selecting my custom configuration when I open file with *.rqs extension
I must open file and select configuration (menu Tools/Select Configuration/My config...) manually.
Can you help me please?

Select your configuration (”Tools | Select Configuration”) and then open the preferences of this configuration (”Tools | Properties for Current Configuration”) and go to ”Association” tab. If ”Enable Association” is active and your desired suffix is defined, EmEditor opens the specified file type with this special configuration.

Thanks !!!

I thought that this settings is only this for association with Windows Explorer.
