Can't make more than two partitions
To be able to create a multi-boot environment you have to revert from a CoreStorage partition layout to a standard partition layout.


Start to internet recovery mode by pressing altcmdR while booting.
Open Terminal.app in the menubar Utilities → Terminal
enter diskutil cs revert LVUUID and hit the ⏎ key.
(LVUUID is the Logical Volume UUID. You get it by entering diskutil cs list in Terminal.app)
In your case it's diskutil cs revert 36635140-167F-4638-BF3C-4477ADAA6B21.
If your CoreStorage Volume is tagged as 'revertible' this command should convert your CoreStorage volume to a standard volume non-destructively.
Enter 'exit' when the conversion is finished and quit Terminal.app.
Open Disk Utility and partition your SSD as you need.
