I don't think it's built in the tools provided. However, since the output is pure JSON, you can easily remove what is unnecessary.
Example:
#!/usr/bin/python2.7
import json
dump = json.load(open("export.json"))
for k, v in dump.iteritems():
if k == "queues":
for i in reversed(range(len(v))):
if v[i]["name"] not in ["QUEUE#0", "QUEUE#1"]:
v.pop(i)
break
open("export-updated.json", "w").write(json.dumps(dump))
