It has been a long time since I’ve done this, but yes, I know that it’s possible, but you need to target the tinyMCE object of the specific field.

I made a modification to another plugin once that was not working with multiple editors and I added this loop to the plugin. The plugin as Sortcodes Ultimate and I added this loop so that it could find the correct editor.

for (i=0; i<tinyMCE.editors.length; i++) {
	if (window.su_generator_target == tinyMCE.editors[i].id) {
		$editor = tinyMCE.editors[i];
	}
}
mce_selection = $editor.selection.getContent();

But that’s the only reference I can find, it was over 2 years ago that I looked at this. Bottom line is that it is possible to manipulate the content of the editor using JS, I just don’t know if you’ll find much help doing it and I don’t know if this information will help you or not.

You may also want to look at the ACF JS API https://www.advancedcustomfields.com/resources/javascript-api/ that has methods to get and set field values. The developer has done quite a bit of work on this and updating fields using the ACF method generally works, but I have not tried it with wysiwyg fields.
