List Segmenting - ERROR when selecting radius

I am trying to segment a list that involves a radius around the winery. Every time I go beyond 10 miles out from the postal code, I get the following error:

Radius for entered Zip Code is too large. Please narrow radius and try again.

Can anyone help solve this? Thanks.

Nevermind. I see that this tool is not available in Canada. Do we have an ETA on when it will be made available?

I don’t think they’ve touched that tool for about 4 years, so I don’t think it’s on their roadmap.
