Change sessions multivariate module

We need someone to change the Multivariate module ([login to view URL]) to our needs. Currently the module applies mutations for the entire user session. However we need to make the mutation permanent (so multi sessions), unless the multivariate test is deleted. For each alternative test we will set a visitor cookie using Google Analytics custom variables. [login to view URL] So, you could test if this cookie is set with a certain user and than show the alternative multivariate node. More information on request. Our issue is explained here: [login to view URL] Should be solved quickly for someone who knows their code!
