Using ArraySize with a pointer to a strucure. Possible?

Suppose I have the following:

struct XMLImportField
{
    LPCTSTR pszXMLFieldName;
    long lFieldID;
};
struct XMLImportRecord
{
    long lRecordID;
    XMLImportField* pFields;
};
struct XMLImportField xmlW2Fields[] =
{
    // XML Field Name Field
    { _T("W2EmployerName"), 27039 },
    { _T("Address"), 27031 },
};
struct XMLImportField xmlW2StateFields[] =
{
    // XML Field Name Field
    { _T("W2StateTax"), 62621 },
};
struct XMLImportRecord xmlW2[] =
{
    // Record ID XML Fields
    { 5002, xmlW2Fields },
    { 22730, xmlW2StateFields },
};

In some function, I could get the array size of xmlW2Fields with
ARRAYSIZE(xmlW2Fields) and it would return 2.
ARRAYSIZE(xmlW2StateFields) would return 1.

But, if I want to abstract this.

XMLImportRecord* pImportRecord = xmlW2[0]; // xmlW2Fields

is there any way to use ARRAYSIZE with pImportRecord->pFields?
ARRAYSIZE(pImportRecord->pFields) generates a template compiler error.
