Starting with Adaxes 2018.2, you can specify custom descriptions for actions in business rules, custom commands and scheduled tasks. If an action with custom description is submitted for approval, the description will be present in the request. For details, have a look at section Custom Description for Actions of the corresponding What’s New article: https://www.adaxes.com/info_whats-new_2018.2.htm#custom_description_for_actions.
The text of the approval ticket cannot be made fully customizable because the description of the operation to be approved is generated automatically and cannot be modified. As an option, we can suggest sending an e-mail notification before sending the operation for approval. So, when a user needs to process an approval request, they will receive a summary e-mail of the operations they need to approve, where you can describe everything using a more 'user-friendly' language. For this purpose, you need to add the Send e-mail notification action before the action that generates an Approval Request.
