[SOLVED] Column Sorting (ascending, descending)

I'm a new RM user ...
When sorting columns in the Results Perspective, the column sort is not 'intuitive' - i.e., not strictly ascending or descending if there are positive and negative numbers. For example,
Attribute PC1
potass 0.107
rating 0.075
fiber 0.005
fat 0.000
sodium -0.983
vitamins -0.101
sugars -0.006
weight -0.001
cups -0.000
IMHO, it would be much better if these data were sorted as in regular spreadsheets, e.g.
Attribute PC1
potass 0.107
rating 0.075
fiber 0.005
fat 0.000
cups -0.000
weight -0.001
sugars -0.006
vitamins -0.101
sodium -0.983
... that way, I (we) could sort a column and quickly glance at the top and bottom of that column to see the max/min values -- which would be especially helpful for much longer columns, where [per the RM default (?) / the example shown above] the minimum value would be 'buried' way up in the table.
Is this possible, or could it be implemented (RM build)? Thanks ...

if you use operator "Sort" before piping to result perspective you can fine tune sorting as
you like it.
