I can see how this functionality would be beneficial to your business. I'd recommend sending a feature request directly to our Product Development team. This helps us improve your experience and the features of the program. I'll show you how:
Go to the Gear menu and then select Feedback.
Type in your feature request in the description box.
Once done, click on Next.
When your employee moves to another location, you may need to set up and pay taxes in that state to avoid any issues. To learn how, you can check out this article: New Payroll Taxes Information.
Fill me in if you have any other concerns or additional questions about managing your employees. Have a nice day ahead.
