Delete Sheets

There used to be a command in CoCreate One Space Modeling's Annotation module called "delete sheets." This command allowed selection of multiple sheets, within a drawing, for deletion. We have not been able to locate this command in version 15.5C making it difficult to delete multiple sheets within a drawing. That is, we are forced to delete one sheet a a time. Say it takes fifteen seconds to delete a sheet after multiple picks to get there and there are 100 sheets to delete! Works out to be about half an hour. Delete Sheets allowed one to select several sheets within the command and then delete them all at once. Thanks for any help. -Stewart
