Need a way to subtract selections

[Dariosky-01]

Salutations...
It would be useful for some ways of using Foundry the "subtract selection" function.
This feature could find a way to exist as it is used with the Windows operating system, because with Foundry I am able to select everything via quick commands, but it is impossible to subtract a selection as it happens in a Windows environment using CTRL plus a click of the left mouse button on the object or item to be subtracted from the selection.
Obviously this subtraction should not only work in the work area but also when I would like to make it act in the list of elements present in the level in the list at the top right where all the objects that make up the level appear.
