Like the other authours have posted,you CAN'T selectively change the external administrative distance of prefixes unless you want to change for ALL external routes on the local router. You CAN selectively change the AD of internal prefixes though as well as specify the next-hop of the prefixes(effective only on the local router as well).
Hope this helps to further clarify.
