Wireshark-dev: [Wireshark-dev] Filter for generated items

Hi I write a dissector DLL, that adds a generated item to the tree. After defining the hf_info with type FT_STRING, i use proto_item_append_text to show the generated string. But this item cannot be used neither to search or to filter for this item.
I have seen, that the packet-frame.c uses proto_item_append_string to 
show the protocol layers. This is also usable in a filter. Since 
proto_item_append_string is not exported, the function is not available 
for my dissector DLL.
How can I either add a hack to my DLL to simulate 
proto_item_append_string or provide another way to filter and find?

Regards,
Helge
