Change Business Title Toggle for Multiple Assignments to Position

Summary

Is it possible to personalize a position name toggle for the employment info screen

Content

We're live with position management and looking to implement multiple assignments. It looks like job titles (business title) are the only way for an employee to toggle between their multiple assignments in the Employment Info screen. The only other way we've identified is by searching themselves in the directory. Is there any way to personalize an identical toggle but using position name or position code?
