Time entered (and handled as data) in simple minutes and seconds.

Using Excel 2003.

How can I get Excel to display and handle entries for duration in minutes
and seconds only (without having to enter a 4'30" entry as 0:04:30)? I have
gotten as far as getting it to display as "04:30.0", but all I need is
single digit minutes (data on this spread*** will never go over 9:59) and
double digit seconds (and to be able to enter them simply as in "4:30"). I
couldn't find that as an option in the ones listed for time in the cell
format dialogue box. Right now I have to enter 0:04:30 in order to get it
to work right. Is there a simpler option?

Thanks.
