How to Choose Snap-plex for Error Handling Pipeline

Hi ,
I have one common pipeline which used to send mail with error details. This pipeline should run on Groundplex.
What I observe, If I use this pipeline as an error pipeline in Parent pipeline which also ran on Groundplex will work. But for those scenarios where Parent pipeline needs to run on Cloudplex, it also executed on Cloudplex by default. I am not able to control its plex.
Can anyone please suggest how to configure error pipeline plex?
