That’s a good idea. Currently, it’s not really available as a built-in feature. You could probably rig up something similar by logging data continuously to the database and then trimming it down periodically based on a separate log of the trigger events. Or a slight modification of this would be to have two tables with the same schema, such as “data_buffer” and “confirmed_data”, and then just periodically insert from the buffer to the confirmed table (“INSERT INTO x SELECT y” - handy sql statement) and delete everything in the buffer.
That said, decent support for this sounds like a good idea.
