Possible to use CURRENT_TIMESTAMP in update function?

[beenotung]

better-sqlite3-helper provides a helper function db.update(table, data, where, whiteList). For the data parameter, we can pass in a key-value pairs to specify the column name and column value.
However, it treats the value as literal value, e.g. db.update('user', {updated_at:'CURRENT_TIMESTAMP'}, {id:1}) will set the updated_at column to be string literal 'CURRENT_TIMESTAMP', instead of setting the column to the current database timestamp.

Work around is to use prepared statement, however that will be much more verbose. In the current design, is there a way to express sql expression on the column value part?
