Icon-based selection for mapping (instead of 0/1 values)

Current situation:
It is technically possible today to achieve selection logic with icons using:

• Spreadsheets with IF statements

• Hidden columns with Palo formulas

• Hyperlinks

However, this approach requires significant manual effort and complex setup.

Current limitation:

• The existing solutions rely on technical workarounds

• Standard checkboxes do not work with dynaranges

Desired behavior:
Introduce a native, user-friendly interaction model using icons instead of numeric values (0/1).

Example:
For a given activity (e.g., Fuel consumption from coal):

• ✅ Allowed & selected → shown with a “checked” icon

• ⬜ Allowed & not selected → shown with an “empty/unchecked” icon

• 🚫 Not allowed → shown with a “disabled/locked” icon and cannot be selected

Additional requirement:

• Units should only be selectable/deselectable where allowed

• Non-relevant units should be:

  • Disabled (non-clickable)

  • Visually distinguishable (e.g., greyed out or with a lock icon)

Value / Benefit:

• Reduces dependency on manual spreadsheet workarounds

• Less manual efforts

• Less error possibilities

• Simplifies maintenance and scaling of mappings

Suggested solution:
Provide a native Dynatables feature for state-based selection, including:

• Icon-based selection (instead of 0/1 or plain checkboxes)

• Built-in logic for allowed/disallowed states

• Conditional enablement based on activity context (e.g. parent elements are not selectable)

• tooltip explanation for disabled items
