Blockchain.info MyWallet API - sendmany CHANGE address

[fraenk]

I have a question regarding the blockchain mywallet API integration.

the documentation http://blockchain.info/api/blockchain_wallet_api mentions nothing about how the change addresses are manged.

I would require the change to be sent back to the from-address?

does anyone have any experiences on this?

also i am wondering about the tx-fees via API, are the min fees really as documented 0.0005, the sites web-interface's custom send form allows to go as low as 0.0001!

Thanks for any feedback here!!
