(NSW)ShallanSoulcaster

what happens if I only have a NSW account, but have planned to only play on PC after cross save becomes available. I can't merge, because that would require two accounts. The Dev stream mentioned a "link" option, but it was woefully underexplained (I feel), is this the replacement for people like me who only have a console account but still want to make PC their main account? so I would be able to "merge"/link to basically a phantom PC account making me able to use the Tennogen I bought on NSW on PC!? Is my interpretation correct? The FAQ unfortunately didn't explain this situation at all (at the time of writing this post).
