regex grep/pipe options

looking for a solution for parsing multiple items in a show command that can
be done without using the grep/pipe.

for instance: show run | section Fastethernet | Serial. Is there a way to
do this with OUT the pipe?

R1#sh run | s Fastethernet | Serial
interface Serial0/0/0
 ip address 10.10.15.245 255.255.255.252
 encapsulation frame-relay IETF
 frame-relay interface-dlci 105 ppp Virtual-Template15
 no frame-relay inverse-arp
interface Serial0/1/0
 ip address 10.10.15.242 255.255.255.252
 encapsulation ppp
 ip ospf network broadcast
 ipv6 address FC01:A28:24:B::/64 eui-64
 ipv6 ospf 1 area 1
 no peer neighbor-route
 auto qos voip
