Yes, you can select multiple commands in the command list (on the "Edit a Profile" window) using the Windows-standard method of holding Ctrl (or Shift for selecting from-to) and clicking the commands (or just pressing and holding the left mouse button, then dragging across multiple commands), then use the "Edit" button or the equivalent entry in the context menu to open the "Command Multi-Edit" window, which allows you to change the category for those commands, among other options.
