Configurable contentUrl for tab?

Hi,

I have created a tab in my custom app. The content of the tab is available at the URL defined in "contentUrl". For example, here is what I have in my manifest file:

"staticTabs": [
{
    "entityId": "TestTab",
    "name": "TestTab",
    "contentUrl": "https://www.abc.com/test",
    "scopes": [
        "personal"
    ]
},

This value of contentUrl might be different, based on the organization using the app. Is there a way to make contentURL configurable? How do Apps published in the Microsoft Teams store deal with this problem?

Thanks,

George
