Got a testnet node synced and set another testned core wallet on the offline machine, then I put the public keys on the online node to see my funds in watch-only mode, but crating the transactions is too complicated if you need to pick specific inputs...

I thought it is possible to assemble a tx completely on live net, with the watch-only address.
Then youd bring the unsigned tx to the cold storage machine, and sign it. Then bring it back to the online machine, and send it... this would remove the burden of manually playing with the in and outs.

Yeah this would be it. I remember reading someone claiming this was possible in the past but I don't know how the steps would look like.

So let's say I have a node online and synced with all my addresses added as watch-only, then the offline wallet in the airgapped computer (both are Bitcoin Core).

How do I make the transaction in the online node's wallet on the GUI as usual then pass it read on the offline machine to sign it with the offline private keys then back to the online node?

If I do the transaction as usual with the watch-only addresses with the ideal fee and all the inputs I want selected in "Coin Control", I can then do "dumprawtransaction" and then make a QR code of this, read it in the offline wallet, then what do I do with this?

I just want to know step by step to not fuck it up in the process.
