How to make EF Core Power Tools generate one-to-one instead of one-to-many relationship

Question

I have a less than ideal data model that is something like this (a country can have no or exactly one central bank):

Table COUNTRY:
COUNTRY_ID: Guid

Table CENTRAL_BANK:
CENTRAL_BANK_ID: Guid
COUNTRY_ID: Guid

Of course it would be better if we head a CENTRAL_BANK_ID in the COUNTRY table, then it would probably work as intended. But now we get something like:

class Country
{
    public Guid CountryId { get; set; }
    public virtual ICollection<CentralBank> CentralBanks { get; set; }
}

But what we want is of course:

class Country
{
    public Guid CountryId { get; set; }
    public virtual CentralBank? CentralBank { get; set; }
}

Is there some way to tell the EF Core Power Tools that the relationship is really 1:0..1 and not 1:N?
