You can create a block for this, or add an additional target frame property to your page/block. This is an example of the block approach.

[ContentType(AvailableInEditMode = false)]
public class PageLinkBlock : BlockData
{
   public virtual ContentReference Link { get; set; }

   [UIHint("TargetFrame")]
   public virtual int? TargetFrameRaw { get; set; }

   public string TargetFrame 
   {
      get
      {
         if (TargetFrameRaw.HasValue) 
         {
            var frame = EPiServer.DataAbstraction.Frame.Load(TargetFrameRaw.Value);
            return frame.Name;
         }

         return null;
      }   
   }
}

The view can look something like this:

@model PageLinkBlock

@Html.ContentLink(Model.Link, null, new { target = Model.TargetFrame })

On your page/block:

public virtual PageLinkBlock MyLink { get; set; }
