[Chimera-users] Can the order of map histograms on Volume Viewer be sorted?

Dear RBVI, Sometimes I accidentally open more than 4 maps into UCSF Chimera session without changing the number of histogram that can be shown to some value higher than the default value of first 3 maps. UCSF Chimera places new histogram on the spot where the 1st map used to be, and the histogram order shown on Volume Viewer goes from - 1st map - 2nd map - 3rd map to - 4th map - 2nd map - 3rd map from top to bottom. I know that I can bring back the histogram of 1st map by clicking on Data drop-down menu, but it doesn't bring back the 1st map to the top slot. Is there any way to manually re-sort the order of the histogram so that it would be in the order of their loading (or in the order of their model ID)? Best, Junha Song.
