Q: How can I create nested or conditional drop down menus in numbers version 3.6.1? Thank you!

I am trying to create dependent drop down fields in numbers so if I were to select "Option A" from column 1, a specific set of drop down fields would automatically populate in column 2. If I were to select "Option B" from column 1, another yet pre-specified set of drop down fields would automatically populate in column 2. Thank you!
