customize selectToolbar ( add other actions instead of just the default delete action)?

There seems to be no option to replace or customize the `selectToolbar`, the default `selectToolbar` only have the `delete all` action

## Expected Behavior

There should be a way to add/remove action buttons to the `selectToolbar`, currently there is no way to do it, or even replace the entire `selectToolbar` component

## Current Behavior

There are no way to add/remove action buttons to the `selectToolbar`, or replace/customize the entire `selectToolbar` component
