How would u like to set a reminder ?

U are a very busy executive. U want  ur  computer cum smart phone to remind u to send an email or meet someone1st thing after u reach office. How would u like Cortana to track u with GPS. Wait till u reach ur office and when u have settled down the reminder comes on ur screen. U would not like the reminder while in transit or u do not want it the2nd u reach office. How would u like to be reminded at the correct moment. Is it a good feature of windows10.
