Ability to copy palettes within own directory ignoring directory filters

When you copy a position palette with ICB info to another palette within position but with the default “P” mask only selected for the position directory, the destination palette is filtered for ICB and an empty item is created. I think if you copy between directory types then masking should be used, but when copying within the same directory type the masking originally applied to the recorded pallet should be maintained along with the data. I think in such cases the mask choices have already been made and should not be applied during the copy process.
