Select/De-select Group Feature (Request/Issue/Proposal)

[JhonJ3]

I believe there should be an option to Select/De-select whole group with a checkbox. Currently, there only an option to select all within a group but not to de-select the group.

For example, if we 've 2 groups Male and Female and if we click; 'Select all: Male', all males are checked but there's no option to de-select all males back.

Another related issue is that clicking 'Select all: Male' would de-select any female option selected prior to clicking 'Select all: Male'. In other words, the functionality works in a way that first the Model is cleared and then all male options are appended. However, it should only append any missing males in the model.
