Bolt/screw/hole wizard in SW is pretty easy to work with
hang on let me get it started for a screenshot
right up there. you generally want to define it prior however.
you can also make threaded holes, through holes, limited depth holes, countersinks, hex cap holes etc. i suggest you keep like holes in groups, apply them when and where then place by clicking checkmark.
looking at your pad it looks like you got the hang of it quite well
