@jen i think if you create a link back to the ITT (ala: ‘created from’) on the ITU record, you should be able to set the default value sourcing for all the relevant fields on the ITU record (ala:

{createfromfield.ittfieldtosource}

. you could send over the ITT id via the URL (ala:

&record.<CREATEFROM>=1234

) and have it all just snap into view like magic.
