Create a remote connection with a custom service account

[joelvilca]

Hi,
I'm trying to create a remote connection for my external function in bigquery.

Following the documentation I see this step to create the remote connection:

bq mk --connection --location=REGION --project_id=PROJECT_ID \
    --connection_type=CLOUD_RESOURCE CONNECTION_ID

By default Bigquery creates a service account for me, is it possible to edit it?
