True DB Column Combinations

The .merge event in the True DB object will combine like-data in the same column to one cell.

Is there anyway to base the merge on 2 or more rows?

i.e.
<original>
1 A
2 B
2 B
2 C
3 C

i want to keep 1,2 and 3 seperate on the grid. if i do .merge on the second column, it will do:

1 A
2 B
2
2 C
3

See how 3's 'C' is gone? Is there any other command or method i can execute to group 2 columns together? Any help would be appreciated.

Thanks
