Can I make Lightroom Classic do not import _display.jpg files?

Hello,

I am new here. I use Mylio with Lightroom Classic - Mylio for management, Lightroom for editing. I prefer lightroom to Bridge+Camera RAW.

When I edit a photo in Lightroom, I can publish to Mylio (Publish Services -> Mylio Photos -> Photostream). That will generate a _display.jpg file which Mylio will display (so for myphoto.jpg it will create a file myphoto_display.jpg). This is all good. But when I want to sync photos from Mylio (they get moved around, etc.) woth Folders -> Synchronize Folder... if I want to sync all changes (which is very convenient for a library of 200K+ photos) all the _display.jpg files will creep back, so Lightroom ends up with a lot of duplicates and does not even stack them - ideally Lightroom would ignore *_display.jpg (or at least ignore when the original is there). I am definitely missing something basic setting here, e.g., just tell Lightroom import all, except *_display.jpg I'd be very happy with. (I know I can batch delete *_display.jpg, but with auto building smart previews it is a waste of computation, waiting, plus an extra step.) Anyone has any tips on this?

I started to write an LR classic plugin to basically import all photos, except *_display.jpg. The problem is that as far as I see the LR Classic plugin API allows me the following:

• LrCatalog.addPhoto - adds one photo
• LrCatalog functions for opening the import dialog (which imports the duplicate *_display.jpg files)

Now LrCatalog.addPhoto is nice, and I created a plugin (menu button) which imports only what should be imported, but it basically runs an import for photos 1 by 1, so importing a 300 photos takes a very long time (~10 minutes!).

It's a long-shot, but anyone has tips what I missed in the API what would be better for this?

I really prefer the LR+Mylio combo, I get backups, sync to devices, wife-friendliness, and Mylio for mass photo management/search is unbeatable.
