Different notes in repeating shifts?

Hello,

I am trying to write a script that can create a weekly repeating shift, but have different notes in each week of the shift.

For example:
1/16/2020 Notes: Week 1 Notes
1/23/2020 Notes: Week 2 Notes
1/30/2020 Notes: Week 3 Notes

I am currently able to make a repeating shift, but have no way of getting individual shifts in this repeated series easily. Right now I can try manually querying each week for shifts at the same start time and end time, but I'm hoping there's a better way.

Is there any way to query shifts by series maybe? I am able to get a series id for a shift so if that query could be made I could make a lot of progress.

Any help is very appreciated!
