You can not have scrolling in four portals at the same time. If you want to have it scroll at the same time you need to have all data in one portal
Thank you Johan. I was afraid that this would be the answer.
You might be able to make a script where if the user picks a row in one portal, the other 3 portals select the same row which might bring them into view. It's not quite the same but it would achieve the result of being able to compare the same data in all 4 portals at the same time. -Amos

One idea is to use a utility table (or even a batch of repeating fields) that give(s) you a filtered display of the real data.
"Scrolling" then would be to move the view, i.e. bring other records into view by having the display records/fields change their contents or (better) reference other records.
This is actually a method you'll find often with calendars or schedules because it means you don't have to create a slot for every day for every day of the year.
Just create a daily / weekly / monthly template that defines itself via user-selectable parameters, then looks up and/or displays the actually existing records/entries for events / appointments etc.
This is pretty much how some of the portal "tricks" work. The scroll is scripted, such that changing one portal will also change the other portal(s). You may be able to find some of these examples here or elsewhere with your favorite search engine.
