You can do a cross ref & limit the list to what you want, for example "Q" (Or "A" if in german) this will give you a cross ref of all that you want or limit to from all blocks.
STL was a favourite back in the days of S5 (FB's could only be programmed in STL), it is possible if the logic is correct to seperate the rungs with BLD255 (***) Segment end, but if the brackets are not correct it will not work, brackets are sort of the graphical way of displaying in ladder in some Japanese they use MPS MPP for the branches.
