Is it possible to use the url.resolveRecord and addParamToUrl to jump to a new custom transaction and pre-fill some fields with a couple parameters? I am really struggling with the syntax. I am trying to follow @erictgrubaugh youtube video 'How Do I Add Dynamic Links to a NetSuite Suitelet?"

although i don't know where this is officially documented, you can add parameters like

record.memo=Default_value

to your url to fill in default values
