The easiest way:
Assume the data is in the range A2:A100, A1 is the column header.
Select cell A1
Goto Data>Filter>AutoFilter
Click the arrow that appears in cell A1
Select CUSTOM
From the drop down that says EQUALS, select CONTAINS
In the box to the right enter: vo
Click OK.
Do your copy/paste
Then turn off the filter:
Data >Filter>AutoFilter (selecting AutoFilter toggles it on or off)
