Basically I'm trying to export a MIRO board via the Vector PDF but I think the miro board is too content heavy - so I've tried just sectioning off the original MIRO board into 4 parts (lucid documents) - I just want to know if there is a way I can merge or combine the 4 different Lucid Documents - into one? I can see an option to insert a lucidchart document but no option to insert another lucidspark document
