Tier2 Dependant Visa, Wife and Child Dependant

Hello,

Thanks a lot every one for you response on my previous post, finally I got my Tier2 General Visa, special thanks to Manci for quick replies, really helped me a lot in making my application.

Now I want to bring my family in UK as Tier2 dependent, my wife and daughter from Pakistan,
My question is: Do I need to submit two different online applications or just one application for both my wife and daughter, if different application then do I need to submit two sets of documents like bank statement my BRP etc?

thanks

Bilal
