Hi ahensley,
Unfortunately this functionality is not currently available within NetSuite. There is currently an Enhancement Request available (419843) for this functionality to hopefully be released in a future NetSuite update. Depending on the type of search you are looking to display, you can create a Custom Record and have the Document Number for the Transfer Order set as “Record is Parent”. This will automatically create a sublist on the Transfer Order record. This functionality works best if you are looking to show records that are related to the Transfer Order.
Please feel free to let me know if you have any questions regarding the setup of the Custom Record. Thank you.
Have a nice day,
