Illustrator on ipad pattern fills

Hi,

I'm trying to get into using the new illustrator app in the ipad.

When i've sent over some existing files from computer to ipad, i'm having trouble saving pattern fills on to the app? It seems i can only use solid colour or gradient.

Is there any way to save pattern fills from imported documents, or create new ones?

I work within clothing design, so i need to be able to fill with prints and textures!

Thanks in advance for any help!
