Hi, Jim Fel.
Thank you for your question. With a 3-setting diverter trim, only the top and left ports will be in use. We recommend a 6 setting diverter trim. We recommend the T27967 6-setting trim kit. Or, you can purchase just the 6 setting diverter cartridge, RP51919, so that all of your setting will work with your existing trim. If you just want 3 individual settings and no shared settings, we recommend to purchase the RP71718.
