Navigating through a cursor

Hi folks,

Lets say I have a cursor and I am passing a Purchase Order number and it returns a purchase order with 100 items.  Now I use FOR function to step through those 100 items in the cursor.  Now lets suppose I have a legitimate reason to jump immediately to the 90th item in the list.  Rather than step through the FOR / END FOR loop 90 times is there any way to automatically jump to the 90th item?  My guess from what I've read in documentation is NO but I thought I would ask anyway.

Thanks,
