Hi @ariznaf
Unless you are willing and able to write a plugin, you are constrained by the current discourse settings, at this time.
First, I would spend some time with the current digest settings and see if you can tweak them to get something close to what you are hoping for.
If something is really important to your business model, you might consider hiring one of the plugin developers here. If you can clearly state your requirements, they can give you a quote over at the meta marketplace.
Maybe “throw those guys a bone” , as we used to say 
Plugin developers need love too
