It is necessary to improve the resolution settings when scanning capabilities

Now the settings is possible to set only two points - a "resolution the text" and "resolution pictures". In practice, often have to constantly change the setting of "resolution pictures" because sometimes you have to scan multi-page color document with 150dpi option, and color photos with a resolution of 300dpi or more. It will be very good if the settings can be pre-specify multiple options with different dpi scanning, such as photo and photo 150dpi 300dpi, which have consistently failed to get into the settings and change them.
