troubles adding strap customization

hey yall,

so I'm trying to edit the catalog_sp file to allow the player to change their weapon strap color at the Gunsmith, but I'm having trouble creating the correct information for the catalog file. There's item keys for the strap colors themselves and all the database items required, but there's no the entries that actually add it to the Gunsmith catalog. Since they're nearly identical to weapon wrap colors, I wanted to derive the source of all the keys of that entry, and the Gunsmith database item looks like this:

                         <item type="ItemDatabaseMenuLayout">
                          <key>0x7638148C</key>
                          <menutype>ITEM_LIST_COLOUR_PALETTE_COMBO</menutype>
                          <menudesc>0xC8654267</menudesc>
                          <hidden value="false" />
                          <flags />
                          <pages>
                            <item>
                              <key>0xEEAA22BC</key>
                            </item>
                          </pages>
                          <menus />
                        </item>
                      </menus>
                    </item>

the strange thing? both menudesc & the top key, 0x7638148C, do not reoccur anywhere else in the file other than these ItemDatabaseMenuLayout items, so I have no idea how to derive it's source so I can do the same to the weapon straps. any ideas?
