DAQmxAddGlobalChansToTask to allow scanning channel twice

Hi,

I was wondering if this would be the correct syntax to allow sampling a channel twice in a scan list:

for (row = 1; row < numrows; row++)
{
   strRow = getstring(row);
   DAQmxCreateAIVoltageChan(task, phychan, strRow, .......);
}

DAQmxAddGlobalChansToTask(task, "1");   // adding row=1 channel to end of scan list

Note that we only need to add one virtual 'row'  to task.

Thank you.
