Foreclosing 2 AZ land parcels with same owner, separate actions?

[Karen D. Schiano]

I am about to foreclose tax liens on two adjacent Navajo Co Arizona land parcels owned by the same person.  Can anyone tell me if I will need to send separate Notice of Intent to File Foreclosure Actions or if I can list both parcels on the same Intent to File and, then, if not redeemed, Foreclosure Action?  Thanks
