Using peripherals connected on Flexbus

How do I define peripherals, or external RAM, that I want to be memory-mapped on the Flex-Bus? I cannot see an appropriate object in the Component Library of the CodeWarrior IDE. My peripheral has a 16-bit wide R/W connection on the flexbus and has 64 consecutive addressable registers. I need to set up base adress, wait states, and to define that I am using a 16-bit multiplexed address/data with an ALE pin. The configuration registers exist in the processor, and I can write directly to these, but I want to use the component library and its built-in checks.
