Several command allow the choice of Project Wide, Drawing Wide and Picking the individual items.
I see one problem with the Pick selection method. It does not allow you to select on more than the active dwg.
If the component pick selection could be changed so as to allow moving between dwgs WITHOUT ending the command, it would allow users to
select components on more than one drawing. As the components are selected, their identification would be added to a temporary list, then when the user has finished selecting, ACADE could then revert to the dwg the command was started on to allow the command to continue from where it paused for the selection process.
