I'm new to FeatureTools library, and I got stuck trying to create two types of features, both are related to fetching previous values. One is the previous value itself for 'QUANTIDADE', 'VALOR_TOTAL' and 'DATA_NOTA', and the other is the time since the previous observation (days) which has 'DATA_NOTA' as the date field.

I don't know if it is possible to do it with FeaturelTools. If someone can help me, I would appreciate it.

I have a dataframe (df) as folowing: enter image description here

When I normalize the above df it takes the following basic schema:

As I said, I would like to fetch the previous values and time since the last observation for 'QUANTIDADE', 'VALOR_TOTAL' and 'DATA_NOTA', but when the combination of 'CODIGO_PRODUTO' and 'CODIGO_CLIENTE' matches.
