Question on Narbik's workbook task | EIGRP Filtering

LAB 4 - Eigrp Filtering (Task 3 page 452 VolI)

"Configure R4 such that it ONLY takes R2 to reach Network 200.1.1.0/24"

First I look from which sources the network is learned

R4#show ip route 200.1.1.0 255.255.255.0
Routing entry for 200.1.1.0/24
  Known via "eigrp 100", distance 90, metric 156160, type internal
  Redistributing via eigrp 100
  Last update from 10.1.234.3 on FastEthernet0/0, 00:02:30 ago
  Routing Descriptor Blocks:
    10.1.234.3, from 10.1.234.3, 00:02:30 ago, via FastEthernet0/0
      Route metric is 156160, traffic share count is 1
      Total delay is 5100 microseconds, minimum bandwidth is 100000 Kbit
      Reliability 255/255, minimum MTU 1500 bytes
      Loading 1/255, Hops 1
  * 10.1.234.2, from 10.1.234.2, 00:02:30 ago, via FastEthernet0/0
      Route metric is 156160, traffic share count is 1
      Total delay is 5100 microseconds, minimum bandwidth is 100000 Kbit
      Reliability 255/255, minimum MTU 1500 bytes
      Loading 1/255, Hops 1

Question

Is this solvable with distribute-list like this: "distribute-list
prefix NET200P gateway R3 in FastEthernet0/0"
where NET200P deny the prefix and allows the rest and R3 matches the
IP address of R3.

I tried it but it didn't work.. any suggestions?
