How to remove Warning from "Confirm Review Meeting Held" Task on Performance Process Flow

Summary:

Our purpose is to remove the Warning message that appears when we insert a future date into "Meeting Held Date"

Content (please ensure you mask any confidential information):

On a performance document, in the task Confirm Review Meeting Held we have to put the date of the meeting, which could be a future date, but when we insert a future date we get a warning.

Our customer would like not to see the warning, is it possible to remove it?

Thanks, Giuseppe
