In 8.4 it'll be possible to do that by declaring the interval as MINUTE
TO SECOND, but there's no way around it in existing releases. I'm not
sure I'd care to rely on that anyway, because any time you provide an
interval value that isn't *immediately* tied to a MINUTE TO SECOND
qualifier, it's going to get interpreted in the more standard way.
I think you'd be happier in the long run if you avoid depending on such
an ambiguous data format.
