the best approach? How do we manage these stored procedures?


As already said, choose proper naming convension. You can add single
prefix for all access procedures to group them visually in the list.
For example, you may use "ZZZ_" prefix to put all these procedures to
the bottom of the list.
Also almost all mordern development tools have a feature to group
objects in the user-created tree. So you may create any kind of
virtual "packages" and fill them as you need.
