advice on displaying a business directory / member list

Question

I have a site with a list of members and each member is listed in a business directory. I am using solspace user to handle my members and display their location on a map.

THe issue I have run into is that some members have more than one location so I need to come up with a method to allow them to add a second location. (and sometimes 3 or 4 additional locations)

What are my options? add many new member fields or build a new channel to handle additional stores?

I laready have hundreds of members with their info already in there, so changing the members with a single store is not really an option. I only need to add on the option of additional stores.

I am using this bit of code in a map widget:

{exp:user:users sort="asc" limit="100" group_id="5" search:shipping_region="NB" search:retailer_type="not Pending|Web"}
    {if longitude}
     {
        "properties": {                         
            "tags": [],
            "phone": "{shipping_phone}",
            "classifiers": ['a'],
            "address": "{shipping_address1}",
            "name": "{shipping_name}",
            "province": "{shipping_region}",
            "owner": "welocally",
            "postcode": "",
            "city": "{shipping_address3}",
            "country": "{shipping_country}",
            "website": "{website}"
        },
        "type": "Place",
        "geometry": {
            "type": "Point",
            "coordinates": [ {longitude},{latitude} ]
        }
    },
    {/if}

{/exp:user:users}

Answer 1

Couldn't you just add a matrix field for "other locations" to allow the user to define their other locations as needed, leaving your existing member location field intact (basically turning it into their "primary" location)?
