Controlling "visibility" of objects - implementation is too restrictive.

Toggling the visibility state of a given object is carried out by the "V" key shortcut.
Its logic is minded as an "on/off" flipping of the object's visibility state.
This logic is fine as long as it is applied on a single object.
.
However - when it is applied on a "selection" of objects - it brings about implausible result.
Applying it on a "selection" would flip the visibility state of each and every object within that selection.
.
Here is a common test case of mine.
Invisible "rest"-s infiltrated unintentionally into my sheet.
Upon printing the sheet they are not seen there.
As a cure - an attempt to set them all into a "visible" state would require "V" on each and every individual rest.
This is a rather tedious and impractical process.
.
Instead - one may propose two additional operators:
"Set Visible" and "Set Invisible".
These will explicitly set the visibility state of all selected objects, regardless of their current visibility state.

.
Putting this enhancement request in the DEV "wish-list" / workplan will be appreciated.

Kind regards
