Read data from the random row of dataSource

When we read data from excel or grid, the data always starts from the first row or the one the user specifies. I'm wondering whether you can add a dropdown to let the user to choose to read data in sequence or randomly (, backward or maybe other possibilities )

This will be a big benefit when we run load testing, in which multiple threads share the data table and run with different data in each iteration.


Thanks
