Many companies I have worked for use a zone drawing view symbol. This symbol displays the sheet and zone of the drawing where a views child or parent is located. Unfortunately the information is typed into the symbol manually because the pos_loc parameter includes both the x and y location together. For example, Sheet 2, Zone 4C. Looking at the standard zone callout symbol one can see that the blocks for the rows and columns of the drawing zones are above and below each other. So, since this is the standard I am proposing that the pos_loc be split int pos_loc_x and pos_loc_y so that the column can be in one block and the row will be in the other.
