Link Multiple Boards & Organize by Top of List of Each Client

Anybody have a way to link multiple Trello boards together, while having it organize the "Master List" in a specific order?

​

I basically use Trello as a project management tool. I give each of my clients their own board where they can submit work requests to me. They organize the requests by most important at the top of their list to least important at the bottom. So, I am looking for a way to link all these boards into my Master Board while putting the cards on my board in the correct order.

​

Example Thought:

\[Master List\]

Card 1 = Client 1 Top-most Card

Card 2 = Client 2 Top-most Card

Card 3 = Client 3 Top-most Card

Card 4 = Client 1 second top-most Card

Card 5 = Client 2 second top-most Card

Card 6 = Client 3 second top-most Card

...and so on...

​

Any help figuring this out would be greatly appreciated!
