Allow filtering of Prioritization list Merged

Currently it's possible to filter the unranked items but it's not possible to filter the actual ranked list under the Epics>Prioritization feature.

As a user I want to prioritize a list of Aha records within a set of filters so that I can manage Aha records in smaller groups and align them with engineering team backlogs.

In Jira a backlog of stories is easily filtered so that the backlog is specific to an engineering team or within any filter criteria.

Having this ability in Aha would really help align with engineering teams and ensure that features are being prioritised properly.
