On most of the CAD Design software I've worked with the spacing gap i.e (pad to copper) is a global value (gap) assigned to each layer, to reassign spacing's per pad or hole size isn't a feature of most software packages. There was/is one that did have the option but its not a common feature.
I use the copper weight of the layer to determine the clearance.
