[Validation errors] Don't display the number of error at each level of the tree when it's unfolded

When there is a validation error on an automation chain, for instance, there is "[1]" displayed in the left menu. When the tree's unfolded, the [1] is displayed next to:

• Automation,
  • Automation Chains
    • the automation chain with the error.

Would it be possible to have the [1] displayed next to Automation only when the Automation part of the tree is folded and have something like:
+ Automation [1]

then

• Automation
  + Automation Chains [1]

and then

• Automation
  • Automation Chains
    • myChainWithAnError [1]
