Unconventional Motion Profiles

I'm trying to produce a motion profile that does not exist in the motion controller. I'm using a festo motion controller and Siemens PLC. The festo controller I'm using has only trapezoidal velocity as basic setup. How can produce another motion profile like high degree polynomials for instance?

I have a Siemens s1200 PLC and cmmp festo controller

Many thanks for help and support!
