A quick and dirty fix for quite a few situations. eg. staged migration of services from global table to L3 VPN.
Bear in mind however the routes you’re importing MUST be installed to the global table from a BGP source in many versions of IOS. eg. you may not be able to import a static from global. Check where your route is coming from and what your IOS version' particular behavior is first.
ip prefix-list P_LIST seq 5 permit 203.0.113.0/32 ! route-map FROM_GLOBAL permit 10 match ip address prefix-list P_LIST ! ip vrf KLUDGE import ipv4 unicast map FROM_GLOBAL !
