Save out Screenshots from within packaged Unreal Product to location

Greetings Unreal Forums! I am curious if anyone would have an idea on how I would go about creating a function that would let me take a screenshot from within an Unreal game, that would save it to a specific area on a computer. A printscreen like function, but not the print screen function. Basically I am working for a client that wants for their VR game, to be able to take a High-res picture of what they are viewing within the game, and save out an image of it, using a command within the game. Anyone have any tips or information on how I could go about doing this?

Please and HUGE thanks!
