Hours Format in Calculator

Hello,
I have a request from some clients that are using columns provided by calculator that results in time values.

Problem:
Every new column we create with calculator, the results comes in decimal with two decimal places. This makes sometimes hard to understand values of hours + minutes or minutes + seconds for some clients. Another point is that you won't be able to see hours, minutes and seconds in the same field.

Idea:
Insert a checkbox to configure the format of the value from decimal to hours: 00.00 -> 00:00:00

Users:
Will be able to understand the values easier and manipulate them inside excel as hours.
