Just make your main component with the pattern that you use most often. Then make as many other patterns as you wish. When your schematic, simply right click on the part, choose "Attached Pattern", and select the new pattern you want. As with most commands, you can apply it to the current component, or all components like it.

During PCB layout, you can not only replace the pattern with any other pattern, you can directly edit the pad properties if you need to. No need to go back to the schematic, though it's always cleaner to have everything match.
