Hey there,
Unfortunately, it is not possible to achieve this currently
If you think this option needed to be added on the core, Perhaps it would be best if you can submit a feature request regarding this issues by creating a new ticket on the forums and set it to "Feature Request" so that everyone else could vote for it.
Or maybe you need them on your site, you can always request for a quote from us at
https://crm.stackideas.com and select "Customizations" . Our sales person would be glad to send you a quote for the customizations that you have requested.
Thanks for your understanding.
