With the current matrix combination plugin, I get links for 'Successful', 'Failed', 'All' and 'None' to select a combination of platforms to build.

What would be extremely useful, is to have the ability to created new sets of platforms. So that there will be additional links 'Configuration 1', 'Configuration 2', etc. which select a different set of platforms. Each of these links should have it's own 'combination filter'.
