Bookmarks (or hack) for User-Defined Events?

[DavidEsp]

I don't use a CPAP but I do use an Oximeter, whose data I load into OSCAR, because of its functionality and ease of use. Works well.

Is there a way to make manually-positioned (in time) notes or annotations of any kind in the Daily charts?
For example I keep a log of waking, getting up, going back to bed, any sensations of note, currently in a text document.
If I see a change or pattern in SpO2 or pulse or explanatory movements, then I refer to my log and would like to enter any that coincide.

If no directly supported for this / proper method, would it be practical (in principle) for me to "hack" my log-notes of interest into the XML file.
If so, then what would be the user-friendliest way to accomplish that?

Many thanks,
David

I created a bookmark, called "First Bookmark Ever". Then, after exiting OSCAR, I tried to string-search for this in all (AFAICT) files imported and saved by OSCAR. However, AFAICT, no files contained that string, so please: where is it stored?

I would like to know where bookmarks are stored (and in what format), not only for curiosity but to see whether I can "hack" a bookmark's timecode, such that when I click it (in OSCAR), the time-cursor will jump to wherever I want.

Any advice welcome

It is a binary file located in OSCAR_Data\Profiles\YourProfileName\Journal_HexNumber\Summaries\.  The filename is a hexdecimal number.

Got it, thank you so much Crimson.
I made a test-bookmark and edited some text into it.
I then found it in the most recently modified such file (and recognised the string format).

Any clues as to the locations and meanings of any other data in that file, relevant to (re-) positioning an existing bookmark in the associated session's timeline, would of course also be welcome.

I suppose the ideal would be a user-defined Event channel, for real-world events such as "woke up", "got up", "back to bed", timestamps (or positions on charts) being free-form. Then could bookmark those Events in the standard way.
