Seeding data into mLab on server startup

I’m currently deploying my app with mLab as my db SaaS

I have a lot data seed on server startup such as meteor_accounts_loginServiceConfiguration etc but it appear nothing is inserted. Beside that, mLab uses ObjectId

Data seed working on local and on production server which having db at the same server

Anyone know how to seed data into mLab on server startup with string id, instead of ObjectId?

Thank you
