Recipient address maps

[Andy Linton]

There's another article that mentions these but doesn't answer the question I have.

In the Web interface under Apps -> G Suite -> Settings for Gmail -> Advanced settings page in the Routing section you can create Recipient Address Maps where you can set up mappings to forward mail to another address or addresses.

This is similar in many ways to the functionality of the aliases file in a number of Unix based mail systems. The mapping consists of entries that look like:

some...@example.com,other...@example.net

some...@example.com,other...@example.net

It's possible to cut and paste lists of such entries to the web interface.

Is there a way to manage adds/deletes to these maps using GAM?
