Hi Team, 

I am currently binding the Timeline component to an array of a custom type. Currently, the only option to display any of the custom properties is to map them to already existing properties of the TimelineEvent interface using the modelFields property.

I would like to request the addition of a designated property in the TimelineEvent interface that references the original data item and allows me to display its properties similar to the SchedulerEvent interface:
