Merging Addresses Issues

When merging addresses, you have buttons to scale down the list by CARRIERS, MAINTENANCE VENDORS, etc. 

Could you add a button for FUEL VENDORS?  Fuel by far is the biggest headache in managing our address list. It's amazing how many different receipt formats ONE vendor can have at each location and they all scan in as a “new” address.

Would it also be possible to select more than one address to merge at a time?  It would help if the address list displayed the actual address along with the vendor's name and city so it wasn't necessary to open each vendor one at a time.

Even though I was being very careful, I also somehow merged an address that overwrote our profile's address for the business.  Can the profile address be protected so this can't happen? Or, can a pop-up message BOLDLY state that this merge would overwrite the profile address?
