We have a client that has a unique need and I'm wondering if it's even possible in FME. There goal is to have a csv or table that contains a dataset name, itemID, and layerID. They also have a GDB file containing the datasets. The would like to have a function to cycle through their csv table, and overwrite an individual layer in an AGOL hosted feature class. The caveat is this hosted feature class may contain many layers and as far as I know you can't update just one layer. We have been racking our brain and FME seems like it may be our last hope.

Here's the short version of the workflow

Read update table -> Read GDB -> Update Hosted Feature Service Layer

Any advice would be appreciated,
