Displaying of User Company next to User Name in any tickets activity log

[sagarika123]

We have a requirement to display User's Company next to User Name in any tickets activity log.
We update the calculated value of sys_user table's name field to add company name. But this also caused the other fields such as caller, created for (in incident) displaying company name.

Is there a way to make this change available only for activity logs but not for any other fields.

 We need the company name next to the user name in the activities. We do not need company name next to caller/created for or any other place where sys_user table is used as a reference table.
