When I use the -EditBlockAttribute command if you answer yes to edit only attributes visible on screen no block attributes will get selected? but if you answer No so that attribute not seen to be included the edit works?

Also why can't I select the blocks or the attributes to be edited with a screen selection i.e. crossing window or fence?

If I use the same command and when asked if edit one at a time and answer yes I can then make a selection individually or with a crossing window?

Can this be Fixed to include a graphic screen selections for the options when using multiple block edits?

Looking for Help

Thanks
