Hi @phanids,
The list can be found by opening the "ConfigTools" option on the top bar menu of MCUXpresso, and then selecting "Data Manager":

1. Unfortunately, no. Kinetis Design Studio was released before ConfigTools, so KDS does not support it.
Do note that your part number does support Clock tool, from ConfigTools, just not Peripherals tool.
2. Manual initialization of the required peripherals is still an option. As you mention, a bit more time consuming but doable.
BR,
Edwin.
