Recording Sled Push & Farmer's Walk exercises

I use the 'free' weight training option on my watch when I start a weights workout at the gym and update the exercises on the web app when I get home.  This allows me to record sets, reps and weight without issue.

However, the Sled Push is a known exercise in the Garmin app (great) but only allows you to enter reps and weight, this exercise is performed with weights over distance.  Is there a way for Garmin to update how this exercise is measured in its web application?

The same is also true for the 'Farmer's Walk' exercise, if this could also be fixed that would be great, thanks.
