Not directly in the schedule, no.

Select one of these items in a model view, select all instances in project, use the properties palette to change the value of that parameter for all selected items at once.

Oh, if it's a sheet schedule, select all sheets in the Project Browser, then change the value of the parameter in the Properties palette.
