Add ability to copy values between rows

It would be very helpful to be able to copy values from one row to another to be able to quickly put a plan together.

For example:

• copy the duration from one row/task to another row/task.

• copy the assignee from one row/task to another row/task.

• copy the schedule from one row/task to another row/task.

This is something that is supported in other tools like Microsoft Project and Smartsheet and would be very helpful here as well. It would allow for quicker plan creation via the keyboard instead of having to click the mouse in the UI to accomplish this task.
