Is it possible to add a comma in between entries in the "Field Multiplier" widget?

In my form, I have a field multiplier widget where responders can submit multiple names of products. I want my notification email to include these product names, but with a comma separating the values and the word "and" before the last value if there are multiple entries. Is this possible, and if so, how would I do this?

Unfortunately, that is not possible. I have forwarded this as a feature request to our back-end team. If this gets implemented in the future, you will be notified via this thread.
