Hi @Ben! Are you talking about the edited config you see stored in the Launchpad view in dagit? This unfortunately cannot be edited globally via GraphQL as it is unique per user (and stored locally).
In general, the config for a job is defined either in code, or when launching the run, so there's no layer in between that you can edit. Just to make sure I understand, is your usecase essentially that you have a database that a lot of jobs read from, but the url for this database may change somewhat frequently (so you'd prefer not to have to push a code change each time?).
One other option would be to load this URL from an environment variable, which might be easier to change on the fly than the actual code of the job (depending on how you have things set up)
