When you have a subgrid on a form and the entity for that subgrid is not also on the 'Related' tab, on the subgrid, there is no 'See Associated Records' command. Instead there is a 'See All Records' command. This is confusing. A user would rarely want to navigate from the subgrid to all records for that entity. The 'See Associated Records' command should appear on the subgrid regardless of whether or not the entity is on the 'Related' tab.
