Is it possible to create custom post types with subtitles?

Question

WordPress

Good afternoon. Tell me, please, is it possible to create your own custom field in WordPress, in which there will be more submenus?
For example, the site has a price list, I wanted to do this, so we go into this field, click create a field in it, it creates a global field, for example, "Painting cars", by going into this section we can add prices specifically to this service, is there any way to do this?

I used to use the old PHPExcel library , but it is heavy, and when it began to pour errors, I found a simpler and lighter version of SimpleXLSX . The only minus of the latter is that she cannot write in excel, but I don’t need to
