Change imported CAN message to be transmitting

Hello! Is there an easy way to change imported CAN messages from receiving to transmitting? I have hundreds of CAN messages in a DBC file, and every time I load them, they default to receiving. I need them to be set to transmitting, but the only method I've found is to recreate each message from scratch in Dewesoft every time I close or change the setup. This process is quite tedious with so many messages and since I also close Dewesoft or change the setup and loose all the messages all the time. Any suggestions?

Dear Simon,

you can select all the messages, right click and select Copy, and then right click and select Paste (swap Rx/Tx) option (hint on page 7 of the manual):
