You can use Cex.io to do this.
Method 1
Mine with cex/ghash. Use their distribute feature to have 10% go to 10 different addresses. All earnings will be divided however you want.
Method 2
Mine with whoever you want. (BTC, bitminer etc). Have their earnings deposited to the CEX deposit address. Then use the cex distribute feature. This way you aren't mining at all at ghash (which some people take issue with), but you can use their distribution feature for free. Only catch is that it introduces at 24 hour delay in the distribution of earnings.
I use method #2. I have different pools all depositing btc earnings at CEX. Once a day cex distributes the btc earnings to the addresses I specify, in the % I specify.
The second method seems to be a great idea. Thinking about doing the same
