Identifying unused columns from a semantic model

Hello! I need help with this requeriment 
In the Power BI service, many published semantic models are used across multiple reports. For example, a single semantic model might be the foundation for 20 different reports. Is there a way to determine, for a given semantic model, which columns are (or are not) being used in all the dependent reports? The goal is to identify unused fields in the model so they can be removed to reduce the dataset size. I'm wondering if there's a general method to achieve this without having to review each report individually??
thanks in advance
