For Powers that Repeat themselves on an adjacent land, can Finder of Paths Unseen use "Open the Ways" before the Repeat to change which lands can be targeted by the Repeat?

For Powers that Repeat themselves on an adjacent land, can Finder of Paths Unseen use "Open the Ways" before the Repeat to change which lands can be targeted by the Repeat?
