Can we add more scroll down buttons?

I want to add more book cover options

Someone has created two other novel covers options before

( https://modthesims.info/showthread....561#post5568561 )

There are only three pages and nine covers in total.

I want to be able to add scroll up and scroll down buttons

Then add more novel cover options

Make a mod with multiple different writing books, just like The Sims 3 writing
