Technical names/keys for select field option values

Is your feature request related to a problem? Please describe.

When reading table data from the Nextcloud tables API via N8N, I get numeric values for option fields back ("2").
The meaning of these values can change when new options are added to a field.

Describe the solution you'd like

When adding options to a select field, there should be a way to provide a technical key.
Example:

• Create new column "Status" of type "selection" (single)
• Add new option "Neu" with key "new"
• Add new option "Gesendet an Geschäftsführung" with key "gf-sent"
• Add new option "Freigabe durch Geschäftsführung" with key "cleared"

To use only a single field, one could split key + title with "|": new|Neu.

This technical keys shall then be returned when fetching row/column data, instead of the numeric option IDs.

Describe alternatives you've considered

Screenshot

When adding a new option value between 3 and 4 (by adding a new option, moving the 4 title to it, and changing the previous 4 value) , the internal value IDs change.

Additional context

Start by tracing the Nextcloud Tables API paths for creating select-field options and fetching row or column data. Determine how technical keys should be stored and exposed, then verify that keys remain stable when options are inserted, reordered, or renamed and that API responses use them instead of numeric IDs.
