Ability to exclude pidtree underlying ps/wmic process from results

[magne4000]

Sometimes on windows (but probably on linux/mac also with ps), I'm having wmic process appearing in my process tree, but I would like to be able to have an option to force it not to show up in process tree.

Here is my use case:

pidtree(process.pid)
  .then(pidusage)
  .then(...);

• pidtree(process.pid) sometimes includes wmic process
• pidusage is executed upon wmic process, but I do not want it
