Custom tab in sidekick dependent on project (app / content app root)

Hi, I trying to add new custom tab (context) to sidekick for some new custom actions. Using AEM 5.6.1 version.

I've made that using CQ.Ext.override sidekick's loadPanel method and onload I used addAction method to add custom buttons. But sidekick is overriden only when clientlib, where sidekick is stored, has defined category cq.wcm.edit. This is a problem, cause clientlib with this category is loaded in all apps, so sidekick is changed independently on app.

My question, is there some possibility to solve this problem?
