multi lightmaps and lightmap switching feature

hi. i was using unity 2017 for my fps game.
since unity 4 i was wating for this amazing feature, but I was disappointed with unity 4, later unity 5, and unity 2017...
It's been two weeks now that i installed unity 2018.3 and for god sake please tell me that this feature is finally added to unity?????? because i can't find it anywhere.
i know that there are some workarounds for that i also did check the unity lighmapswitcher plugin in github but it's complicated. we need a simple and safe solution.
so tell me if there is any feature in unity 2018 about multi lightmaps and lightmap switching. if there is no, please someone from unity make us happy by saying it will be in unity 2019.
This is a long time expected feature.
Thanks.

 

indeed this is a long expected feature.
I hope it comes to Unity 2019.

 

i don't know if they fully understand the Importance of this feature.
i checked their roadmap and there were nothing about multi-lightmaps or lightmap switching.
