Is it possible to access the joined table in a field updated event without having to add a loop so that you can access the PXResult<> object?

For instance, a graph that looks like this:

 public class MyGraph : PXGraph<MyGraph>
 {
     public PXSelectJoin<Detail, InnerJoin<Header, On<Detail.hdrId, Equal<Header.id>>>> MyView;

     public void _(Events.FieldUpdated<Detail.someField> e)
     {
         //TODO: find the Header record that is joined to the Detail record that fired this event?
         
         /*  Don't want the overhead of doing something like this:
         
         Detail dtl = (Detail)e.Row;
         foreach(PXResult<Header, Detail> res in PXSelectJoin<Detail, InnerJoin<Header, On<Detail.hdrId, Equal<Header.id>>>, Where<Detail.id, Equal<@P.AsInt>>>.Select(Base, dtl.Id)
        {
             Header hdr = res.GetItem<Header>();
             //more code here.
        }
        */
     }
 }

This is for 22 R1.

TIA!
