Welcome to Shopify Community. My name is Olivia and I work here.
I appreciate you sharing that screenshot with us! It helps me get a better understanding of what you are after, and how to best help you today. From your question, I am not sure if this screenshot is from customer accounts on your site, or if this is an example of what you are after. If this is on your website, have you added these fields through custom code, or through an app? Any details you can provide around this, such as which tutorial you may have followed, or which app you are using, are super helpful.
There are typically two ways to allow your customers to have more flexibility and control over their account, orders, and more through a self-management section in their account.
A) Hire a Shopify Expert
Hire a vetted third-party expert to custom code these self-manage features into the front-end of your website. You will get complete control over feature requests, and consulting with an expert directly will allow you to explore all of your options.
B) Use an app from our App Store
There are a tonne of great apps that can add features to customer accounts. They are easy to install, manage, and can get you what you need in a matter of minutes. Check out some apps that I shortlisted for you as options:
Some of those apps even offer return shipping labels which can save you and your customers time and money. Make sure to compare their features and check out the app store for our full offering. It's also a good idea to bookmark our guide on getting support with third-party apps if you require any extra assistance with set-up or app specific questions.
Please let me know if this is what you are after, and if there's any further support or advice I can offer.
I look forward to connecting,
My pleasure, @Antonkalin!
Don't hesitate to reach back out to me if you have any further questions.
