VBA Excel如果在字符串开头出现数字，请替换数字的最后两位

我试图将数字的最后两位数字替换为“ XX BLOCK”，如果它出现在字符串的开头并且超过2位数字。

我正在使用Microsoft VBScript正则表达式5.5参考。

Dim regEx As New RegExp
With regEx
    .Global = True 'Matches whole string, not just first occurrence
    .IgnoreCase = True 'Matches upper or lowercase
    .MultiLine = True 'Checks each line in case cell has multiple lines
    .pattern = "^(\d{2,})" 'Checks beginning of string for at least 2 digits
End With

'cell is set earlier in code not shown, refers to an Excel cell
regEx.replace(cell.Value, "XX BLOCK")

所需结果：

"1091 foo address"      --> "10XX BLOCK foo address"
"1016 foo 1010 address" --> "10XX BLOCK foo 1010 address"
"foo 1081 address"      --> "foo 1081 address"
"10 bar address"        --> "XX BLOCK bar address"
"8 baz address"         --> "8 baz address"

我是regex的新手，不确定从哪里开始。我尝试使用，^(\d{2,})但随后替换了整个数字。

还可以保证数字（如果存在）将始终带有空格。
