Make stacked preview annotations generate showkaseMetadata components for each annotation

README.md

@@ -173,6 +173,7 @@ to understand the behavior when you don't pass any properties.
 **Note:** Make sure that you add this annotation to only those functions that meet the following criteria:
 - Functions that don't have any parameters
 - If it does have a parameter, it has to be annotated with `@PreviewParameter` that is provided a `PreviewParameterProvider` implementation.
+- Stacked `@Preview` and `ShowkaseComposable` annotations are only supported with KSP at the moment. This is because of this [issue](https://youtrack.jetbrains.com/issue/KT-49682).
 
 This is identical to how `@Preview` works in Compose as well so Showkase just adheres to the same rules.
