What would be the best way to make the default drop functionality (from one Gantt into another) use Copy instead of Move?
So, basically I would like to use the CTRL + Drag row as a default when dragging a row into an another Gantt.

Is there a configuration setting for this somewhere?

In the docs I found 'GridRowReorderConfig.allowCrossGridDrag.transferData' but no examples for copy, and I haven't been able to make it work. Is this the preffered method of achieving the copy functionality? If so, could you supply a simple example of using the copy function?

Note: Currently the copy method only works when dragging when CTRL key is pressed. We should add a simple config to handle make the row drag behaviour more configurable.
