Show a field on menu

Is there a way to show a field from a table that applies to that user?

Here is what I am trying to do. I have my truck pm table that does all the calculation of when a service is due in miles. I would like to have that due mileage Just show on the menu page for only that person to see when they login so they know how many miles are left before the service.

I am thinking I have to build a code snippet?

Thank for any ideals on this.
