One recent addition to the AGOL / Portal system that I love is the ability to publish a hosted feature layer and a vector tile layer at the same time, in such a way that the two are linked.
If the feature layer sees significant updates, a user can go into the vector tile layer settings and rebuild the tiles with the latest data, refreshing the vector tiles in place. This is a considerable improvement over the earlier republish-and-swap workflow for updating vector tiles.
My question: if I have a hosted feature layer and a vector tile layer published from its features, but which were published before this feature was added, is there an easy way to establish that link? I have a few vector tile layers that I use all over my Portal, and I would love to refresh their content from their corresponding hosted feature layer, but I don't want to republish either, given the workflows and public viewers built on top of them.
