Display Folder as a Map

In Journey you can check on 'map' within a folder and see that collection of routes all visible together.  But I have some questions..

1.  Is there a way to use this a backdrop for actually planning a route (so I can see that collection of optional routes on screen as I map out my actual chosen route).   I've got published GPX's of Gravel and Touring routes between same destinations (some too big to import) and want to make my own by harvesting parts of those routes as I do my planning.  (ie Opting for gravel where I dislike the road, but using the tarmac where I'm happy).

2. Rather than having to manually trace each of the routes I'm harvesting from (to get them into a folder) is there a way to simply gather the little collection of GPXs and have them appear as multiple traces.   It would so good to have them all visible (ideally fairly faint) so I can do my design.  

Thanks

Private and Favourite POIs

Is it possible to add private POIs to the cycle.travel map? 
This would be great when researching/planning routes… a way to highlight the things I would most like to see (or consider diversions to include if time allows)….  Nice looking cafes etc.   

Product suggestion Camino del cid spain

Product Suggestion: You show the 2000km cycle touring route for El CID already. Did you know the gravel version is now published by the El CID Camino organisation? It’s pretty handy to harvest both routes to concoct a mixed route (tarmac roads where they are quiet, but diverting to gravel to include beautiful bits or to avoid busier or less attractive road sections). We are doing that as we go but feels like cycle.travel might like to have a look at publishing the gravel route as part of the standard. Keep up the good work …. We just keep discovering more and more about the brilliance of cycle.travel
