OSPF external routes summary

RouterOS General
1

Hello, I have this network topology:

router0(ASBR) --link 10.2.128.248/28 – router1(area 2)

Router1 is in area2 and have 3 interfaces. On each interface are is subnet eg. 10.2.128.0/28, 10.2.128.16/28, 10.2.128.32/28. On this subnet are client CPEs with staticaly routed sunbets eg. 10.2.129.0/28, 10.2.129.16/28 etc. until 10.2.140.0/xx. OSPF between router0 and router1 works perfectly, bud I need to summarize subnet on router0 on 10.2.128.0/20. I think MK have not a possibility to summarize external routes. Because if I put 10.2.128.0/20 to area range on ASBR, only subnets on eth1-3 are summarized, no staticaly routed, they are redistributed to the network.
Please is there any chance to summarize these subnets, or not? I have many sites with this situation and I have about 1000 items in routing table.

Thanks for an answer

external routes cannot be summarized. set those networks in separate area and then use area range.
