Shop Slider - Number of products shown

Hey guys,

I'm working on a client site using BeTheme. To highlight featured products, I put a shop slider on the shop page above the product categories.
The shop slider only shows 3 products at a time, while the product categories are displayed with 4 items per row.

Is there any way to have the shop slider also display 4 products at a time?

See attached screenshot!

Thanks for any input!
