How to handle error occur on child visual script from parent visual script?

Hi everyone,

I have a parent visual script named A, inside A I have inserted many visual script like B, C, D. If one of B, C or D having an error during I run A, how can I handle this error from A?

I know how to use "Error Handling" for each visual script, but I want a solution more generic, I don't want to add "Error Handling" for each child visual script.

Is it possible? Please share with me any possible solution.

Thanks in advance.
