Please enable specific coordinates for motion ( Ken Burns effect

Please allow size and position coordinate to be entered to match up start and end frames. Currently it can take hours to match up the start and end of clips so where the clip ends and the other starts are in the same position. Using your finger to move the end to match up with the start of the next clip is frustrating. Even on an iPad where the image is bigger it's still hit and miss. I've tried adding a dissolve transition to hide the mismatched change but it doesn't work that well. If there was a way to type on the end and start positions of motion it would be life changing when using rush.
