Going back to an option in Activity Diagram

Question

I am using the Activity Beat code.  I want the arrow that comes out of Modify Details to go back to Validate Registration Form instead of the diamond.

@startuml

|Swimlane1|

start

:Fill Out Registration Form;

|Swimlane2|

:Validate Registration Form;

 if (Form Valid?) then (No)

|Swimlane1|

:Modify Details;  

|Swimlane2|

  

  else (Yes)

    :Add Detals to System;

  endif

:<<datastore>>\nUser Database;

|Swimlane2|

:foo5;

stop

Answer 1

It may be possible using Goto now.

But it's still beta.

Search for it on Q&A because it's currently not documented.
