Expected FLOW: We want to avoid overwriting and instead store the latest document along with the previous ones in the document library.
Information Required: How should we store the information? Should it be done with date and time stamping only, or should we also update the names?
Suggestion: Storing folder information with date and time stamping seems preferable. Updating names might create confusion.
formatDateTime(utcNow(),'yyyy')
formatDateTime(utcNow(),'MMMM')
