Mister SD7,
I am not sure this will help but here is how I organize my registrations.

After creating a group of registrations the SD7 OS assigns them a number such as
[004]. The registrations are organized in numerical order. I don't like to use numerical order so I connect my SD7 to my computer and delete the numbers from the name of the registrations. Now the registrations are organized in alphabetical order and they stay that way. If I later add more registrations and fill up a page they will continue on a following page which is normal.

Hope this helps.

Deane
