If user (admin) can have rights to config some settings like reminders for quarterly / annual appraisal. Or to change the template of existing notifications as such. Thanks.
For sharing your ideas, we will definitely take this into consideration.
But, regarding editing the templates of existing notifications that we have, it’s possible under the 'System Settings" option.
System Settings --> Miscellaneous --> Mail Template List! You can customise the existing ones here and in the meanwhile we will get back to you with custom reminders like the one you asked!
