Document validation rejection reason

Hi all, 

I am looking to build a child bot that I can insert into a Document Automation Process. I want the child BOT to make decisions based the selection made during validation, ie:

1. wrong document type
2. cant read document
3. other: <free text>

I have spent a LOT of time today trying to pass the ValidatorUI output to the child BOT but in all cases the dictionary that is passed down has no records. 

There must be way to access to this data, any feedback would be much appreciated. 

For bonus points: Is there a way to create additional rejection options?
