How to implement the annotations' feature "Convert to Multiple Parts" in C#?

[FabianOrtega]

Hi,

I need to implement the ArcGIS Pro annotations' feature "Convert to Multiple Parts" (see Image #2) in my code C#, but I didn't find how to do it using the ArcGIS Pro SDK for .NET, I don't even know if it's possible. So, does anybody know if it can be achievable through the Pro SDK? And if it's the case, how?

Thanks,
