Form Validation Errors (Grouping)

[eluser]RS71[/eluser]
Hello

How could I group certain form validation errors together so the errors returned are not repetitive?

What I mean is -- lets say the user submits a blank form, instead of displaying "The ABC field is required." over and over for every field in the form, how can I just say "Every field in the form is required." in the case of the 'required' rule for example.

I'd appreciate if anybody could point me in the right direction.

Thanks in advance.
