Field service technician resource needs to have multiple addresses to ship part replenishments

Summary:

Field service technician resource needs to have multiple addresses to ship part replenishments. Technician address is setup at resource directory level as attached in the screen shot. Once this address is updated, technician is visible in Create part request page for replenishment.

We have requirement that technician can have multiple addresses where parts can be shipped like his home address, nearest UPS or Fedex warehouse from where he can pick the parts shipped to him.

I tried multiple imports from Resource to address imports. resource import does not allow me to import multiple address through import job. I can update all address from Resource Directory UI as given in screen shot.
