Is there any way to show more details on the course map?

I have a Garmin Fenix 6x pro watch. I downloaded the map from alltrails app for my hiking. The map shows only one line of the course. There is no any other line. It happened several times that at the cross road, it is difficult to tell which route to choose from by just looking at the map on the watch.  I will need to look at the alltrails map on my phone, which shows a lot more details, especially the other tails. So that I can decide which route to take. 
Is there any way to make the map on the watch to show more details, similar to the map on the phone?
