Wireshark-dev: [Wireshark-dev] Question: dissector tree display construction

I have made a start on writing dissector plugins for a couple of protocols

My question is whether it is possible to add an item to the protocol tree 
without registering it.

Standard code for an item looks something like this
static int hf_hpi_hdrsize = -1;

static hf_register_info hf[] = {
	{ &hf_hpi_hdrsize,
	{ "HPI PDU size",      "hpi.hdrsize",
	"", HFILL }

	proto_tree_add_item(tree, hf_hpi_hdrsize, 
				tvb, offset, 2, BYTE_ORDER_LITTLE_ENDIAN); 
	offset += 2;
Is there a way to do this in one step without having related hf_register_info 
and static int?
	proto_tree_add_somehow(tree,"HPI PDU size %d", 
              tvb, offset, 2, BYTE_ORDER_LITTLE_ENDIAN); 
	offset += 2;
My protocol has about 200 different commands + responses, each with different 
field interpretation.  I don't need to filter on most of these, so I'm 
looking for a more succinct way of generating the tree.
