Is there a way to change the default settings for a module

Hi… I would like to redefine the default settings for the bb modules. For example, I need to redefine the default margins and colors for the Heading module.

I know that I can put in some CSS to override the settings, but sometimes that can get really tricky to get just the right selectors. So I would rather just redefine the module settings.

Is there a filter (with example) that can be applied to redefine a module’s default settings?
