Describe the issue

I run the script for the environment of 500 dags. It is extremely slow, it takes more than 1-2min to do this for each dag. I has taken almost entire day and not yet finished. Is there a better way to batch those requests and pause multiple dags at once?
This has to be done before the snapshot can be created.
