Vizlib Writeback different keys

Dear community,

I would like to use different keys in the same Vizlib Writeback table.

An example:

Key definition

• Key1: Country name
• Key2: Country name + City name

Use/Logic

Table is containing Key1, Key2, Checkbox, Text (Comment). Lowest granularity is Country + City.

• Checkbox: Only using Key1 which means all check boxes belonging to a country get the check if applied
• Comment: Only using Key2 which means the comment will only be stored for the Country + City combination

Is it possible to assign different keys to columns in the same table to achieve this scenario? If not: Is there another way to achieve that with Vizlib Writeback?

Best regards,

Dario
