I would like to be able to have multiple Syncthing folders with the same local location to have their own unique ignore files. Currently, if I change the ignore file of one Syncthing folder, it affects the ignore file of the other one, because they are the same physical .stignore file in the same local location.
You can. The .stignore file is not synched.
Personally, I prefer for all Devices to have the same Ignore Patterns for any given folder, but that’s me and my use case.
I don’t follow. The folders have the same path, so I wouldn’t think the .stignore has to be synced for them to be shared across the folders.
My apologies, I misread your question. Restating your question to confirm my understanding: You have multiple Syncthing Folders for the same directory on one of your Devices.
You cannot, in this case, have two different ignore patterns for those two Folders. While the .stignore file is not synced between Syncthing peers, you have just one of those files in the directory.
You can have different ignore patterns on the devices on the other side, though.
