Ability to export garmin checklist, edit it on mac and import it back into the app

Hi,

I’ve been trying to export a checklist to edit it on my Mac, but I haven’t found a way to do it. The only file I get is a .gplts file, which I can’t open with any known editor.

Is it possible to do this?

I have some aircraft checklists in .ace format, and I’d like to edit the Garmin Pilot ones to avoid doing everything manually. After editing, I’d like to import them back into the app. Is that possible?

I saw that some time ago this could be done via the website, but that option doesn’t seem to be available anymore. Was that functionality removed?

Best regards,
Guillermo
