You can manually reverse engineer your schematic from the PCB, netlist and BoM but there is no automated way to do this in EasyEDA.
It seems to obvious now. I tried searching for this, so thank you for pointing it out.
Brand new interactions and interfaces. 
Easy to use and quick to get started. 
No.
