Bulk Contact Import API

I am building some code to import contact data from a separate site.

When I create a Kentico contact, I'm just setting the basic data such as email, first/last name, company name, etc.

When I do a bulk insert, it throws SQL errors about some of the fields that are usually automatically set, such as ContactCreated.

But if I fall back to inserting them one-by-one, it works fine.

Here's an example similar to what I'm doing:

//'contacts' at this point is a List<ContactInfo> of uncommitted contacts (with basic member data populated)

try
{
    ContactInfo.Provider.BulkInsert(contacts, new BulkInsertSettings
    {
        // BatchSize = context.BatchSize,
        Options = SqlBulkCopyOptions.Default
    });
}
catch (Exception ex)
{
    //fallback to single insert
    foreach (var contact in contacts)
    {
        await ContactInfo.Provider.SetAsync(contact);
    }
}

In this example, it'll always fall back to the single-insert version unless you populate every value, and the single-insert version works and populates those fields on its own.

Is there a BulkInsertSettings parameter, or something like that, that will cause the bulk insert to run whatever 'additional' logic is happening in the single-user version?

I'm doing the same thing with ContactGroupMemberInfo and EmailSubscriptionConfirmationInfo, so I'm worried that there are side effects that I'll run into by using the Bulk Insert for the three of these.
There are tens of thousands of contacts and subscriptions, which is why I want to use bulk.
