Drag the window with trackpad pushing the key

Hi. I have a request to improve this one thing.
I'm using Trackpad and dragging a window by moving cursor on it with keep pushing the particular key. i.e) shift key
However, the dragging speed was much slower than dragging a window with keep clicking the windows.
I hope this situation will be improved.
