We have been trying for months to get this to go working with Esri teams and we are still stuck. I thought I posted as an idea but I guess not.
We have a org wide ArcPro toolbar with all our shared tools on it that has been great. But it only allows regular toolboxes and not geoprocessing services. This means we have no way to share these services out. Regular toolboxes are rather limited in needing the correct packages, have to backhaul data to Pro, and need for extension licenses. Geoprocessing services solve all of these issues. But with no way to add to a toolbar or even favorite the services we have no way to get them to our users besides a search in the Portal section of catalog.
Seems like it would a pretty easy add so hoping this can happen. We want to be able to use geoprocessing services toolboxes anywhere we can use toolboxes really. Should be interchangeable.

Thanks @KoryKramer for looking into this!
thanks a lot
