Hello @dh201hy,
Currently the theme does not have the feature to set the service section using the Posts .
Unfortunately, the theme doesn’t support this customization and, as much as we would love to help with some custom code, this is beyond the support offered for our products.
Our suggestion to you is to hire a professional developer for your customization, so that your theme will no be effected in any way.
To hire a developer please follow the link below

We hope you understand.
Best Regards.
