Hey @epoberezkin

This feature would be great! 



Is there any way how I can support you solving this issue? Can you show me a point of entry solving this?

Or maybe is there kind of a workaround to use the inline function during data validation? Especially this is my use case. Accessing the data for validation.

Kind regards
