You can create profile regions so that several properties are included in a single group then used in merge rules. Profile regions are required only if you want to use unique merge rules on specific property groups. If profile regions are not required, you can ignore this configuration and specify NONE in the merge rules profile region field.

Type. Select Mergerules as the type. The other options are for future use only.
