Sum Min Values?

I have a report with one row group. In one of the fields I am displaying a Min value

In the totals row of my report is there a way I can Sum up all of the Min values?

Category Limit
X                3
Y                4
Z                2
Total          9  <<<This is what I cannot do

So something like: =Sum(Min(Fields!Limit.Value)) but this doesn't work

Thanks to any help in advance!
