Error on Saving an absence

Summary

The users when they Save an absence they must get a custom warning message to Submit the absence to process it further not the standard warning.

Hi,

I have a requirement where a person having a particular role can only apply the absence. Now that part is done at my end using 'Global Absence Entry Validation' Formula type.

I wanted to understand that when a particular role attempts to SAVE an absence record, instead of submitting, is it possible to show a custom warning message?

As of now in the system, there is a green dialogue box that appears to notify about the Saved absence. This is the dialogue box where I am looking to customize the message.
