Did you ever get a resolution to your question?

By values of a filter, do you mean the list of drop down entries that a user would choose in the filter?

If that is what you are asking and assuming your dashboards are all  built from the same cube, you can share filter values across the them  by creating a KPI class ( Extends %DeepSee.KPI) that contains all those shareable common things like filters or actions. Then extend the cube class with this KPI. This way the items of the KPI become available in the dashboards and then it is just a matter of attaching the individual items to widgets of the dashboard.

 At my current job, we do not have local installations of Cache. All  developers work on a single windows server which serves as a development environment. There is no source/version control or central repository. I am wondering if there are source control clients that would allow several users to work off different branches but on the same machine, so that each user has their own "local" version of a repository..We want to introduce source control, branching and code reviews. However my experience with this has only been in situations where each developer has a local instance of Cache on their laptops. Any ideas on how we can solve this?
