Generate one input from multiple selections with aldeed autoform and simple schema

I would like to create a form where the user is able to select multiple options from multiple “topics”, that returns values that are later concatenated into one single input field, the content. What I’m aiming for is to create a base content from the selections that could later be treated as a single input that can be freely updated at a later point. The content should become a draft that the user later on is able update without being restricted by the different components that the content was originally depended on.

Essentials = new SimpleSchema({
aboutUs: {
    type: String,
            autoform: {
                options: function() {
                    return empData.find().map(function(obj) {
                      return { label: obj.aboutUs, value: obj.aboutUs };
                    });
                }
            }
    
},
evPreText1: {
    type: String,
    autoform: {
        options: function() {
                    return PreTexts.find().map(function(obj) {
                      return { label: obj.TypeText, value: obj.TypeText };
                    });
                }
    }
}
});

Instead of inserting the texts that are returned from the db into aboutUs and evPreText1 separately I would like these two values to be passed to a single “content” input, and nothing should be inserted into the separate fields, is this possible somehow?
