Once the patch is applied you can run:
./symfony doctrine:data-dump --classes="Member,MemberType"
And get:
data/fixtures/Member.yml
data/fixtures/MemberType.yml

Or, if you want one yml file:
./symfony doctrine:data-dump --classes="Member,MemberType" --individualFiles=0

Thanks, man! It helps me alot!

Great job! Saved me big hassle.
