title: How to write ForAllMaps function
body: <p>I want to write code that checks, if source has <code>id</code> and destination has <code>SourceNameId</code>, than map, otherwise ignore. For example <code>Company.Id -&gt; CompanyDto.CompanyId</code></p>
  
  <pre><code>ForAllMaps((typeMap, mappingExpression) =&gt; mappingExpression.ForMember($"{typeMap.SourceType.Name}Id", o =&gt; o.MapFrom("Id")));
  </code></pre>
  
  <p>Now <code>mappingExpression.ForMember</code> throws exception if cannot find <code>SourceNameId</code>.
  It should not ignore all others members, mapped automatically or manually later</p>
