Wrike Proof | Allow guest user mail-invitiation to send to a bcc mail-address

When inviting guest users via mail (without a wrike guest account), we have to write our mail text within the text field in the Wrike invitation popup and enter the clients mail-address and name.

Could you allow to tick eg. a box that sends bcc mail to Wrike admin/member in order to be able to archive this sent mail in our normal email-archive in MS Outlook or Apple Mail. Alternatively it would be perfectly OK if we could enter a BCC-mail-address in the Wrike invitation popup.
