Use alternative browser for em Client links

I would like em Client to open web links in a different browser from the system default. 

Having reviewed the forums I know this isn’t possible. em Client always uses the system default browser. But it would be very useful for people like myself who use a work laptop for volunteering or other personal use and have to use different browsers.

It would be a nice feature if this was possible. It seems to be a common question, and would be filed as a feature request.
