Hello Data Science people!!

I will come straight o point. I recently joined as a data analyst with a hospital and we are expanding the number of employees that work for us. My role is to analysis employee work related data like how many hours they worked, how many customers they seen and site wise analysis based on with site they have seen the customer. Online or a telephonic encounter and stuff like that. We have data all over the place and while I am gradually unifying the data, I do not store the data like on monthly basis anywhere yet. My thinking is, If im spending 30 mins cleaning for a single employee for the whole year, why not store that month data in a data base under that employee name and keeep adding additional months clean data as they come up. Lets say in dec I was asked to do an year analysis, these monthly data can easily be merged and create a dashboard rather than having to copy paste the dataset and spend days cleaning. Imagine doing this for 50 employees? I wanna tell my manager about this idea of having a single drive for data where we have different folders for each employee and within those folders we store monthly data (since its only 2023 data). Down the road lets say we have 5 years data, in that case we can start storing data on yearly basis. Im scared my manager might think this is a stupid idea. My manager and team are more than impressed with my work in just a month but I wanna keep that impression that way.

Please tell me im not crazy!

Thank you so much
