Limit of waypoints in Google My Maps

I recently found out you could make maps in Google My Maps to track the route you took.

I want to map out the driving directions I took for a trip a few years ago, but I am only able to add 10 waypoints though (A – J), then I had to make a new grouping/batch of directions.

I was wondering if it was possible to add more destinations direction/points then just 10?

In the photo attached, I want to merge the two groups of directions into one big list.
