Ability to change spacing height and width at same time in repeater

[Boldline]

Would it make sense to add an option to lock the settings proportionally? Or an option to edit both numbers at the same time? It seems right now the user would have to edit the width and then go edit the height of the spacing

@Boldline I added this to the backlog, but not sure if it can make it into 1.3
