title: separate serial numbers for related records?
body: <p>Normally a serial number would work where a record gets created and it can auto create that number in the sequence for all records regardless.  What I'm trying to determine is whether there's any way, perhaps a calculated field could work, where there's a separate sequence number that can start from 1 for records in a relation to a parent record (key = key).  For example, key=11 has child records that have sequence fields starting from 1, and similar to key=12 or any other number respectively.</p>
  
  <p>Any help or guidance on this question shall be gratefully appreciated as we want to display a rank in those order as created.</p>
