Ability to hard-code a column value

[simonw]

I realized that sometimes I might want to e.g. extract structured data from multiple sessions into the same table (e.g. a table of summarized topics from audo transcripts) into the same table, while maintaining a column that can be used to tell which transcript is which.

So there should be the ability to set a column to a specific value for every imported row.

This should be a thing that can be set with a query string, that way I can build apps that link to the page in a way that pre-fills a column.
