Unfortunately, you cannot tune this type of compensator in SISO Tool and preserve the compensator structure.
There are other MathWorks tools you can use for this:
1. Create a representation of this controller in a masked subsystem in Simulink and define custom tunign behavior as explained here.
2. Use Control System Tuner in Robust Control Toolbox. It lets you tune custom fixed-structure controllers.

right, the PI usually is equalto Kp+Ki/s but the PR=kp + ki s/ s2 + ω2 so you need to take the block function and type the transfer function inside, but you need to do script file for your model like mathematical equation. and you can use sisotool to tuning the tf I have this help
