How can I panelize different designs onto the same panel? I have tried doing what you see below and telling JLCPCB that the order contains 4 different designs, but the agent I spoke to said that the panel wasn't created correctly because there should be one outline with different sections connected with mouse-bites. What is the best way to create this within EasyEDA?

I know it would be easier not to use this "different designs" approach but I am using quite a few common ICs, crystals and inductors which are part of the "extended" range in these ESP32 based boards, each of which has a slightly different design. Therefore I would like to pull them all together onto one board so I don't need to pay the $3 per extended component fee for these re-used components.
