Send original row and edited row values to a function

Is it possible in the context of Apps to not only send the edited row values to a function, but to also send the previous/og values of the edited rows to the function (e.g. via the payload attribute)? The aim is to have both the modified and the original version of the row in the function (without having to load the data table with the original entries via OD Python SDK in the function). Any ideas how to solve this? :thinking_face:
