sbr/trust question regarding property assignment

will be finalizing my trust this week and submitting sbr on form 1 via efile. have searched for an answer to this question, do i assign the item to the property schedule prior to scanning the trust or after I get the stamp? Just wanting to get everything wrapped up and submitted this week. Thanks in advance.

im wondering the same thing but mine is a suppressor that doesnt even exist yet

Supposed to ad it before you take possession.

i will be building a suppressor going to get my trust noterized today so i do not need to add anything to my schedule a/assignment sheet until the item have been approved and tax stamp in hand because i will not even start construction until i have recieved tax stamp is this correct.
