Easiest way to add a new kext into OpenCore?

Hi,

If I want to add a new kext into my EFI > OC > Kexts - is the easiest way to place the kext into EFI > OC > Kexts and then use Propertree to perform a File > OC Snapshot ?

It feels right but I wondered if this would duplicate all my existing Kexts found in the snaphot process or it would simply appended the newly added one.

Thanks,

Steve
