@nqk: Now that the cloud connection fetches custom columns built from other columns, you can use a template that automatically computes the names.
One example template:
Code:
program:
val = field('#myint');
first_non_empty(
cmp(val, 6, 'very small (0-5)', '', ''),
cmp(val, 11, 'small (6-10)', '', ''),
cmp(val, 16, 'medium (11-15)', '', ''),
cmp(val, 21, 'large (16-20)', '', ''),
'very large (>20)');
