Question

I need to map a list from destination object to source, using a public method on the source object.

e.g.

public class Destination
{
    private IList<int> List = new List<int>();
    public void Add(int i) { List.Add(i); }
}

public class Source
{
    public int[] List { get; set; }
}

So in pseudo-pseudo language the mapping should be:
Mapper.CreateMap foreach item in Source.List, invoke Source.Add(item)

Can this be done?

Yes. Use the ConvertUsing syntax:

Mapper.CreateMap<Source, Destination>()
    .ConvertUsing(s =>
                    {
                        var d = new Destination();
                        foreach(var i in s.List)
                        {
                            d.Add(i);
                        }
                        return d;
                    });
