1) Yes. Storing in the computer is the default. For easy organization, make a folder, such as "Scans" and one of the last steps before scanning is selecting where you want to save it on your computer. It will remember it from the prior scan, so only need to do once unless you have another group you want in a different folder.
2) Sort of. After scanned, can go into the folder and change the file name from the default IMG(number sequence) to whatever you want. However, writing a blurb , not under, but technically on the picture, or in the border under, would require some special photo software with text capability.
