Unfortunately, without specific knowledge of the "Stock Works" program, it is difficult to provide an accurate answer. However, one possible solution could be to input a very small quantity (e.g. 0.001) for the stock when setting up the owner as "void." This should allow you to record the voided, never issued certificate while still satisfying the requirement for a quantity input. Double-checking the program's documentation or reaching out to its support team could provide more specific guidance.
