select all/none button on tables

[lsmith77]

Is your feature request related to a problem?

in (insights) tables the checkbox values are tedious as I tend to sometimes want to drill down on only a few rows which can require a lot of clicks

Describe the solution you'd like

a button in the header bar to select all/none

Describe alternatives you've considered

Additional context

select/unselect checkbox values seem to be persisted on (insghts) tables which means even a reload does not help

Thank you for your feature request – we love each and every one!
