Changing the EIGRP Administrative Distance on Incoming routes

Does anyone know of a way to change the administrative distance of routes
that are redistribute into EIGRP? For example, routes are redistributed
from BGP into EIGRP, and will receive the AD of 170 when advertised to other
routers. The routing table of the router running EIGRP/BGP has the distance
of 20 - understandable. When redistributed into EIGRP and passed to other
routers - the idea is to change this distance from 170 to 90. The goal:
have EIGRP place the route (over 34mb pipe) in the table over the
preexisting routes across a lower speed links with lower AD's.
 
EIGRP has two main options for changing distances - using the "distance"
command - where you can specify a source interface, or the "distance eigrp
<int> <ext>" command - which will change the distance of internal and
external routes.
 
Since there is no EIGRP interface for the redistributed route - using the
first option means having to configure this on receiving routers, which
could mean quite a few routers to touch.
 
Regarding the "distance eigrp <int> <ext>" command - is this a locally
significant configuration command, or is the route propagated to the next
router with the value I specify?
 
Thanks all.
Shawn
