Hello @saysi-travel! Welcome to Plotist!
This is actually something that we do not currently have available. It is a fantastic idea thought and it is now on our list of features to add to the timelines! :D Perhaps something involving importing as well. I'll bring this to the team. :D If you have an idea of how you would like it to function, like clicking on a track, or simply being able to create a copy to edit, or what have you, let us know! :D
