Adding Another Column to DataTable in Google GanttChart

[Mick 16]

Greetings,

I wanted to add an extra columns such as Budget Done, so that it will be shown on the tooltip when we hover at the bar.

Example as attached in the screenshot:

Under Resource, i would just like to add another column...

Is it possible if we add new one?
