Marvin Infinity handles for top sash

[wojtoj]

I have recently installed some Marvin Infinity double hung windows. Overall I like the windows but there are no handles to lower the top sash. I have to make sure the bottom sash is closed then carefully put my fingers next to the glass on the top sash and push down, once it is down about 1/2 inch I can pull it down from the top. Do they make any kind of handle for the top sash or am I missing something?

thanks
