Yes, you can.  Set the length to 0, initially, and then use
"proto_item_set_len()".

See also "proto_item_set_text()", which is useful if the subtree header
is to contain a summary of the items in that subtree; you initially
create the item with "proto_tree_add_notext()", and then set the text
later.  (Make sure you *always* set the text.)

See "packet_dns()" for some examples of how those are used.
