How to? Sign raw transaction on blockchain.info wallet?

[prophetx]

I'm testing some of the new capabilities of mastercoin.  we have a utility to generate a raw transaction (http://mastercoin-explorer.com/selling_offers/new) but some of the users are using blockchain wallets and we cannot figure out an easy way for them to sign this tx with their private key on their blockchain wallet (other then exporting the key and using bitcoind).

does anyone have any suggestions?

does blockchain.info wallet have some way to import a raw tx string and sign it?  I looked around but could not find any such utility.

thanks!

Prophetx, You will need to use Bitcoin-qt to sign the raw transaction.
