To Jon (& others),
To be able to add the Pin-Drop flag (a check mark actually) to your standing sheets, you will need to customize your standing sheet since this is a non-standard rule and not on any of the predefined formats. If you have never customized a report or standing sheet, then start by looking at the BLS-2015 manual. It is available via the Help tab at the far right edge at the top of the screen. Then go to page 189, or via the Table of Contents going Reports->Standing Sheets->Layout.
Once you are ready to modify your standing sheet, the closest instructions are on page 192. The element you want to add is under the 7th grouping called "Additional Average Information", and the element itself is "Below Book Average Flag" It becomes two columns labeled True Ave and Pin Drop when it appears on the standing sheet.
Place it onto your standing sheet in the position desired and save the modified standing sheet off. NOTE: as the software will advise/warn you, this will change all instances of this standing sheet across *all* your leagues. So if you process more than one league and only want this for some, you will need to be careful.
Hope this is enough detail for anyone familiar with the BLS report formats to add this detail to their standing sheets. If not familiar, take the time to read the few pages on the topic in the manual. It is well written and will help you quickly gain confidence in altering reports for your specialized needs.
