Currently, you can only use 1 shipping option. An alternative will be using multiple payment forms or using the coupon code.
You might consider creating a separate form for the international or domestic and combine them in 1 form. Please refer to this guide:How-to-Create-a-Basic-Multiple-Payment-form
Please check this thread (https://www.jotform.com/answers/406970) where Neil used the coupon code function to deduct the shipping in case it should be a pick-up item. Now, here's the guide about the coupon code: How-To-Add-Coupon-Code-in-the-Payment-Form
Hope that helps. Thank you.
