Managing the same elements across several Selection Sets currently requires repeating the same operation for each Selection Set individually.

I suggest adding Selection Set Groups, allowing users to group multiple Selection Sets and manage their memberships in a single operation.

For example, a group called “Model Calibration” could contain:

• DMA 01

• Calibration Area

• Critical Pipes

• Field Measurements

After selecting one or more model elements, the user could right-click the group and choose:

Add Selected Elements to All Selection Sets in Group

The selected elements would then be added to all four Selection Sets at once.

The same concept could support:

• Remove Selected Elements from All Selection Sets in Group

• optionally, Select All Elements from Selection Sets in Group

The group would simply reference existing Selection Sets rather than act as another Selection Set itself.

This would significantly reduce repetitive work, save time when maintaining complex models, and reduce the risk of forgetting to update one of several related Selection Sets.
