Circle select

A minor request. I might be a rare user of circle select, nonetheless I have found it difficult to use in conjunction with grease pencil strokes while using a stylus. By default it uses either mouse wheel or numpad +/- to adjust the circle radius. I think it would be great if were adjustable in a similar way to stroke radius using the F key and dragging the cursor but it actually is even quicker to use C+move cursor. I am able to make this as a custom keymapping but I think it would make sense to have it included as a default. thnx
