Robyn on granular level data and model

Hi Robyn Support Team,

By Default, Robyn builds a National level model where input data is at week level or month level (weekly, monthly or daily data). The question is can Robyn build the model at customer_id X year-month level of data?
If so what are the changes to be made and how accurate and complex would the model be?
Is it feasible to run on customer_id level?
