Want to add another seperator to a row of unique values

From a look up field a have a row of values which are in my case dog breed subscriptions. I cropt this row by using the Array unique functions so it only shows unique vallues. Some rows have just one unique value of some have for example 3. I want to seperate always the last value in a row with an & or and instead of a comma.

For example

Bernese Mountain Dog, Rhodesian Ridgeback, Labradoodle → Bernese Mountain Dog, Rhodesian Ridgeback & Labradoodle

Rhodesian Ridgeback, Labradoodle → Rhodesian Ridgeback & Labradoodle

Does anyone now a solution for this problem?
