How to support “convert program list to vst presets” in Cubase?

As a developer, how can I make sure that this Cubase-specific feature is supported from my VST synth plug-in? Is there anything special I need to be aware of, or do?

This feature is for old VST2 plug-in with programList.

Is there any way to convert say Serum presets to Cubase vstpresets?
