You would need some thing like:

ip vrf VRF
 import map VRF-IMPORT
 route-target import 123:111
 route-target import 123:222

! import specific routes from VRF
route-map VRF-IMPORT permit 10
 match ip address prefix-list VRF-IMPORT
 match extcommunity 2
!
route-map VRF-IMPORT permit 20
 match extcommunity 1

ip extcommunity-list 1 permit rt 123:111
ip extcommunity-list 2 permit rt 123:222

ip prefix-list VRF-IMPORT permit 10.220.0.0/14 le 32
