If the name appears on other cards, or it's a known different language alliteration (like we see with Russian names), it can be added as an Alias to the main profile, then when this new spelling is in a new checklist, it'll automatically link. The other option is to take the PID of the main profile, edit the different name and add the PID.
I just added "Andrei Nestrasil" as an Alias to the main Andrej profile, so now if you go back, edit the name on the card and save without touching anything, it'll link.
