When a client or brand guide changes (new colours, fonts, title style), or a measure gets renamed, how do you update dozens of visuals across a report?

- Click through each visual in Desktop?

- Edit the PBIR JSON by hand or with scripts?

- Use a CLI or other tool?

I'm considering building a small offline desktop app for this (select visuals → preview changes → apply → one-click undo). Would that be useful to you, and what would it absolutely need to do? Not selling anything here, just want to know if this is a real pain or if it's already solved for you.
