The way it works in RKLogoEdit is if you want to jump over a picture for example you get a .lst entry like:-

ItemName=FM
ShortDesc=Radio
ItemDesc=FM RADIO
ItemID=940
ItemType=1
SubType=0
ItemFlag=0
ItemRect=0,0,240,320
OffSet=-1,&h11D0

whereas a sequential entry would be :-

ItemName=FM
ShortDesc=Radio
ItemDesc=FM RADIO
ItemID=940
ItemType=1
SubType=0
ItemFlag=0
ItemRect=0,0,240,320
OffSet=-1,0

note the difference in the line "OffSet=" , the "relative offset"

This method could be used for the dancemammal editor too to jump over pictures or only choose selected pictures.
