Export to TDP Local Storage Field Length

Hi. In my auto script, I have to write to Local Storage a field, potentially thousands of characters long. I don't see a way to set field lengths in the export task. Manually, I can send the results of a query to LS and choose "longtext" but that's only 570 char long.

Soon, I'm moving this job to export the results to TIC, and likewise, I don't see how I can set the field length. As it is, I'm being cut-off at 341 char.
