Yes and No.
The 2 buttons on the schedule in the attached image lets you select in floor plan (left button) or 3D window (right button) all the objects that are grouped in that cell row.
So as long as all the objects you need to change are groped together (Merge Uniform Items) then you will be able to do what you want. The trick I use sometimes is to have temporary schedules that I edit to get the objects to merge.
In your case I would create a temporary schedule that filter "object type" and "custom parameter" and use that to select them.
