How do I trigger a snapshot when using changelog write mode in pipeline builder?

I’m using the changelog write mode for an output in pipeline builder and need to trigger a snapshot transaction on this.

The documentation says snapshotting is possible but I’m not able to figure out how to do it in the Pipeline Builder UI: https://www.palantir.com/docs/foundry/building-pipelines/maintaining-incremental-performance/#changelog-datasets

Can you change the output mode to default for one build (it should snapshot output) then change it back to changelog?
