Designing a breakout for crenellated (castellated?) pads
I've only heard the term 'castellated' used for this type of feature.  Unless more detail is provided with that footprint (specifically the pad dimensions), you can create pads that resemble that footprint, leaving a reasonable gap between each pad.  E.g. the pitch is 1.3mm so the pad width could be ~1.0-1.1mm and pad height or about 1.5mm looks about right.  Then just arrange them as shown in the footprint drawing.  I don't normally use a footprint wizard unless there are a lot of pads.  In this case you could probably create it manually quicker, especially since it's not a typical package.
