I use grid lines in most projects for structural grids. Grid line labels within a file may not be duplicated for good reason. However, when adding grid lines to an existing sequence and attempting to edit the label value for chronological sequencing, I sometimes receive an error message "You have entered a label value that is already in use." My issue is that I cannot find the grid lines with that label anywhere in the file after checking all design layers, viewports, using custom selection, etc. Is there any way to locate a grid line with a specific label, or override a label, so that it can be deleted to allow proper sequencing of other grid lines? Thank you for any help.
