You can create a full copy of selected project components (Tables, Fit Plots, Figures and entire Folders) by selecting Create a Copy item on context menu.

If the only Fit Plots and Figures are selected for creating a copy, the created Fit Plots and Figures will use the data from the same tables and columns as the initial ones. If you select also the Tables which contain plotted data, then the created Fit Plots and Figures will use the data from created copies of these Tables.
