• Create two UI elements (preferably radio buttons) which allow to select between “by query” and “by instance”.
• Display a Tooltip, which describes the difference between both selection types, when hovering over the elements.
• Select the “by instance” option, by default, to prevent the user from performing the batch operation on all instances that match the query.
• Change the instance table view, depending on the selected mode:
  • By query:
    • No instance checkboxes are shown.
  • By instance:
    • Instance checkboxes are shown.
• Unselect all instances displayed in the table, by default.
• Disable the button to get to the next step by default.
  • Enable button if at least one instance is selected.
• If the “select all” checkbox is checked, show an info (blue color) notification displaying the amount of the selected instances on the current page and a link to select all instances that match the query, independent of the current page.
  • Show the info notification only if pages are > 1.
  • If this link is clicked, change the selection type to “by query”.
    • Display an info notification with a warning that continuing leads to creating a batch operation that affects all instances and a link to unselect all again.
      • Show this info notification when selecting "by query" and regardless of whether "select all" is checked.
      • If this link is clicked, change the selection type back to “by instance”.
