HI,
I'm trying to merge my bitcoind coins with some of the coins in my trezor.
According to this
https://bitcoin.org/en/developer-examples#complex-raw-transaction you can create transaction and sign it on several passes till it states complete.
So I've created my transaction with the inputs from the bitcoind and the trezor and sing the part from the bitcoind.
But when I load the transaction in electrum to sing the inputs from the trezor I don't get the sing button.
Is there anyway to accomplish this?
