Individual Labeling of Tasks

[rosanzheng]

Hey there! First of all - thank you for providing this great package!
For my use case, it would be great if the labeling of the task displayed in the timeline could be given another value other than the already given task-name.
Is there a possible workaround or is this only applyable by creating this as a new feature? If so, I'd be very happy to contribute this additional feature.
