Divided QR-code for Electrum

[allin58]

Hi. I develop hardware wallet which interacts with electrum.
An issue is that - eink screen is not able to reflect whole qr of signed trinsaction
size 400x300 pixels. one qr dot occupates 4x4 . sometimes it is not enough even to reflect one simple tx with one input and one output.
Is there way to divide QR to several part? I mean does electrum assums part of signed tx?

Why not add an SD card option, ask the user to download the file after signing it on that memory and then create it with any device connected to the Internet to broadcast it?

yes I used sd card in pervious version of wallet. for second version I am going to implement airgap connection through QR interchange
