So looking at the code of InsertField, it looks like there isn't an obvious way, unless there's some way to chaining SMTs to achieve it.
Question then is, is it worth adding it to the InsertField SMT? The change looks reasonably straightforward, and I'm happy to do a PR if it fits with the aims of the project. My use case were records keyed on the topic by user id, and I wanted to persist them into S3 with the user id as part of the one JSON object per line data.
