Thank you for your post.
You can set up a script that attaches to a button that will display the next set of 25 records. The script would include:
If [ Ceiling ( Get ( RecordNumber ) / 25 ) * 25 + 1 ≤ Get ( FoundCount ) ]
Go to Record/Request/Page [ No dialog ; Ceiling ( Get ( RecordNumber ) / 25 ) * 25 + 1 ]
In essence, this checks to see if records exist in the next block of 25 records (you don't want to try to go to a record that does not exist). If so, then go to the first record of the next group of 25 records.
If you need additional clarification, please let me know.
