How To Implement Plugins through Adobe Launch

I want to deploy various plugins such as:

getTimeParting,getDaysSinceLastVisit,getLoadTime,getPercentPageViewed in Adobe Launch.

I am adding this in Configure Tracker Using Custom Code in Adobe Launch inside

/* Plugin Config */

s.usePlugins=true

s.doPlugins=function(s) {

    /* Add calls to plugins here */

}

But it is stopping normal Event based rule and Page load rule to send Adobe Analytics Beacon call.

Any suggestion will be highly appreciated.
