Home Page Element question

I am testing RT 6.5 and was curious if it is possible to add to the “full page slider” in the Home Page Layout section. Currently you can input 4 sliders but I would like the ability to add a few more, would this be possible?

I have tried third party sliders (Metaslider) which was working nicely in 6.3 but with the changes to 6.5 the padding is off and I really don’t want to change the css to change the padding and the stock slider does what I need except for the limitation of number of slides.

Thanks for you help.
