There is currently no way I can use TEXTLIST function with both unique values AND mapping.
- Either you can use parenthesis function with UNIQUE property
- Or aggregation function with mapping but with entries repeating. To sum up both use cases are incomplete.
Please add option to turn on both features at the same time:
- Either add additional attribute that would implement List mapping
- Or add another aggregation function like [UNIQUETEXTLIST: X] that'd deleting repeating entries.
