Tiled Gallery Link to setting default

Although I am careful to check carefully, I often miss choosing the Media File option for Tiled Gallery link to setting. The visitors cannot click and see the large images although I ask them to do so. Is it possible to have a default setting that we can choose to be active all the time. For me, it would be “Media file” others may choose something else. But doing this for every single tiled gallery block is a bit tedious. For me, that is!
