Favourites on default joomla articles

Hello,

I am here due to the favourites feature of the flexi content. It works perfectly when articles are transfered to the flexi contant. Is it possible to add this feature to default joomla articles (the ones I imported to flexi)?

I can't find any other extension which works like this one. The reason why I want to use it on standard joomla arts is that articles can be viewed as a not list but preview in category section. Hope you can give me some tips, love your work!
