Of course. There is an option in the add-in called Custom list, which randomly fills the range with values from standard Microsoft Excel custom lists or from your own list.For example, you have 50 names and need to pick random 10. Just add all 50 names to your custom list, select 10 blank cells in Excel, click Generate and get 10 random names picked from your Excel list.
Besides, the utility allows to create a custom list from your random data. Suppose you have a list of names in a worksheet. You select this list and click New list. That's it! Just one click and you have a new list added to the Random Generator. Now you have it among your Excel custom lists.
