Misusing settings is key to getting the most out of Fusion
Do the horizontal offsets need to move as well?
If you have less than 8 lines you can create this by using tabs for your text.
Every tab can have a seperate value so you'll get variable spacing.
Or if it's just to set it up, you can use Character Level Styling.
Add a CLS modifier, then select every line seperately and then use the alignment slider to adjust the horizontal off-set.
