Scatter Map Zoom Settings When Outputting Dashboards

Has anybody found a way of setting how zoomed in a Scatter Map is which sticks when you leave the dashboard or output the dashboard as a PDF/image?

In a lot of instances when the map feature would be of benefit to us we need to be fairly closely zoomed in on South Wales. Whenever I try to output this dashboard though, or leave the dashboard and return to it, I end up with a much wider view of Western Europe with only a few small dots crowded together too close to really gain any insight from. If I output just that widget as an Image the zoom setting seems to stick, but when I try to output the whole dashboard it doesn't. I've tried adding Country and the various Geo Areas into the widget filters but there still doesn't seem to be any way of affecting the zoom other than manually within the platform. 

Here's the view I need...

Here's as close as I can get when I'm outputting the document...

Thanks in advance for your help. Interested to know whether organisations in the US/elsewhere have similar issues with the zoom, or whether this is just a regional UK problem?

Cheers,
