Method to automatically put one sample row of dataframe into context

Is there a method to automatically put a single row of each of your variables into cursor’s context when you are speaking to it? Similar to how it has document context? It is very annoying to constantly have to show it a snapshot of my data to get it to process it correctly, or to give it many rules about the data to follow.

For example, when you have a time zone data, it can really have a lot of trouble with different types of dates (string, date time, time zone aware, etc)
