Wallboard and/or filters for deployment plans

It would be nice to have wallboards and filtering for deployment plans, in the same way there currently are for build plans.
We have a significant number of deployment plans. The All Deployments page is very slow to load. It would be nice to be able to display only the relevant subset of plans instead of displaying all plans.
For example, if there are several related systems there could be a wallboard showing the deployment plans for only those systems. A release manager could have a wallboard which shows only production deployment environments and no development environments.
