How to Add/Create FPM GAF Roadmap Steps Dynamically??

Hello Experts,

I have a requirement where I need to create Roadmap steps dynamically in FPM GAF.

I have a Initial screen with 4 radio buttons , based on selection of radio button I need to create different number of steps in GAF FPM.

I understand that we create dynamic steps using Rodamap UI elements in Webdynpro without using FPM.

However have to use GAF FPM and create steps dynamically.

Kindly let me know if this is possible or not. OR if there is any other alternative for this.

Thanks
