ASP.NET C# Code optimization to make it generic

I have a root Web API project and some other side class library projects where other apicontrollers are defined ( each project is a seperated webservice for external communications ).

Each side project has its own controller which has a BuildModel function where we do the mapping between the external webservice models and the models used internal.

Example of the BuildModel:

        // Get AX Customer
        OrderRequest order = ....
        var customer = order.Customer;
        var axCustomer =
            _customerService.GetCustomer(
                _mapper.Map<Customer, AxCustComSetup>(customer)
            );

        // Vendor
        var vendor = new AxVendor() { AccountNum = "11111", Name = "VENDOR" };

        // Get AX Articles
        var articles = _mapper.Map<IEnumerable<OrderLine>, IEnumerable<AxComArticle>>(order.Order.OrderLines);
        articles = _articleService.GetArticles(
            _mapper.Map(vendor, articles).ToList()
        );

        // Create EDI Journal and return true if succeeded
        var ediJournal = _mapper.Map<AxCustomer, AxComEdiJournal>(axCustomer);
        _mapper.Map(vendor, ediJournal);
        _mapper.Map(order.Order, ediJournal);

        var ediJournalLines = _mapper.Map<IEnumerable<AxComArticle>,
            IEnumerable<AxComEdiJournalLine>>(articles);
        ediJournal.Lines = ediJournalLines.ToList();
        ediJournal.CreateDate = DateTime.Now;
        ediJournal.OrderId = string.Empty;
        ediJournal.Remark = string.Empty;

        return ediJournal;

Basically, we need to make a AxComEdiJournal object which is then used in operations with our database.

For each side project we almost have the same identical method except for the external model types which is used to do the mapping.

Can we make this more dynamic or generic because now I copy paste this into other projects and change the model types.

For the mapping I use Automapper.
