Grid Macro Block Migrate to Element Types

[ProNotion]

Looking for some advice or inspiration on how to approach the need to convert Grid Macros to BlockGrid content but in a more detailed way than is currently possible (as far as I can tell). I need to do some content type switching depending on what the actual macro is and not just treat all macros equally as at the moment they will all be converted to BlockSettings_Macro. For instance - I have an element type now called Slideshow and if I am migrating a Grid Macro that is a Slideshow macro then I need to make sure I map the properties to the new element type.

I can map the properties ok using the GetPropertyValues method in my ISyncBlockMigrator but I can't switch the content type in that method.

@KevinJump Any advice on how I might achieve this?
