Blockchain.info merchant API, taking money out of a receiving address?

[Cyclone]

Hi, I was wondering if it was possible to remove money from a receiving address (based on label) and redirect it to another labelled address, using the blockchain.info merchant api  (http://blockchain.info/mywallet_api).

There doesn't seem to be, so how could I keep track of balance within any given label? Which addresses would sending come from?

If that's not possible to track or do, what services could you recommend which CAN do this? I'm essentially looking for a secure, online wallet service with a full API which allows you to do essentially everything the bitcoin rpc can do.

Sorry if this is in the wrong place!

EDIT: Some additional info: It seems as though you can do that manually on blockchain, so why can't you do it via the API? Did they simply forget to document it?

I added a from address parameter to the api. Also you can now interchange a label and a bitcoin address (So both the to and from address can also be a label)

e.g.

https://blockchain.info/merchant/abf66471-fe0a-6820-8977-55d7e8c1f6b2/label_balance?password=$mypass&label=Donations

is analogous to:
 
https://blockchain.info/merchant/abf66471-fe0a-6820-8977-55d7e8c1f6b2/label_balance?password=$mypass&label=1AJbsFZ64EpEfS5UAjAfcUG8pH8Jn3rn1F
