Add filter by feature in release gantt Merged

I am managing cross-functional projects and I need to include in my Gantt some of the features from the product team. I currently can filter them at the lowest level by release, which will show all the features of the release. Most of my projects are related to some specific feature of the release but not all of them.

In other words, I need to copy the feature from the product team which forced me to remember all copied features and track all changes that could occurred. 

This filter already exist for the custom roadmap and will be more than helpful if it could exist in releases=>gantt.
