NY has an allocation worksheet for days worked out of NY. Generally speaking, it serves to transfer some of the NY state wages to the home state. 

i used to use it for NY non resident employees who would have business trips outside NY (the intended use)

The worksheet is based on total working days, weekends, etc. You may be able to make it work…. Note that days worked from home are not permitted 

edit: this would be strictly a workaround. Make sure your on firm ground and document the w2 is incorrect
