Allow master feature filters on a strategic roadmap Merged

The strategic roadmap is great and exactly what we need, except the DETAIL is a master feature yet you can't add a master feature filter. For us its a deal breaker and we've been forced to create custom roadmaps to kind of get the same thing, but not really.

If the master feature is visible, it should be filterable in our minds??

Example: we have a custom field (suggested by Aha) that is a boolean to show if the epic is a placeholder epic for the release itself. We'd love to only show these on the strategic roadmap at certain times, but cant filter them out. At other times, we only want to show epics that have a certain status eg Those in dev.
