better ui for load to object

I sorted this out on my own, but it wasn't super apparent from the get-go what I was doing with the Load to Object UI. 

What is updating what here? When the results weren't what I expected, I have two choices: 
1. Keep trying until it's right, guessing and checking
2. Try to find the documentation

What I would love to see is some sort of verb that tells me what I'm doing. Like:

Update FIELD in the object with VALUE. It seems backwards the way it is now. 

I now know that I have to read this UI from right to left, select the field on the right that you want to update with this value on the left.
