More Filter for Roadmaps

Currently, Roadmaps has only 3 filters, done/ todo/ progress. 

It's too small. I have some Epic which should be managed differently in one project. Hence I can't filter them on the Roadmap I am considering the separation of the project. 

If you add some filters on the Roadmap, it will be really helpful. 

Also, it would be extremely useful if project administrators could add custom filters based on fields available in tickets belonging to the board.

In addition to this, it would be helpful to have filter options by Category, project lead, period and issue number
