Dynamic URL display on sublist

Hello there,

I am trying to mimic the behavior of the work order creation from the sales order. I think I passed the url creation with parameters. (Not sure, this is the best way to do it though).
However I can't find a way to use "linkText" for only one link... I don't want to see the complete URL but only a linkText.
Does anyone knows how to do it? (I created a custom column in the item sublist with hyperlink type). LinkText seems to work only on the "form", not on the "setsublistvalue".

 var AF = url.resolveRecord({ [INDENT]recordType: 'customrecordgci_fca_acknowledgementform',[/INDENT]    [INDENT]recordId: currentRecord.id,  isEditMode: false[/INDENT]   });    soRecord.setSublistValue({ [INDENT]sublistId: 'item',  fieldId: 'custcol_create_af',  line: i,  value: AF[/INDENT]   });
