The Data Tree View has a right-click context menu from which stations can be deleted, duplicated, or moved to a new loop. Multiple stations can be selected by holding down the shift key (these operations won't work when non-adjacent stations are selected, as can be done by holding the control key).
Delete survey
Deletes the current survey (the highlighted survey; not necessarily the selected survey shown in bold).
A station can be renamed by right-clicking it and selecting Rename station. Or, press the F2 key. A dialog is shown that gives the option to rename just the selected station occupation; all instances in the current loop; all instances in the current survey; or all instances throughout the campaign.
Deletes one or more selected stations (stations must be adjacent in the tree view). To restore deleted stations, data must be reloaded from a text file.
