I agree with modifying your preview for the new year AND SAVING THAT WITH A NEW NAME. Then assign your sequences to use the new preview. So I have a Christmas 2020, and Christmas 2021, and Christmas 2022, etc. Some years I may even have more than one. If for example I start 2024 sequencing in February and use a Christmas 2024 preview based on anticipated changes for 2024. Come summer when I am actually changing props and end up building a bit different than what I anticipated six months earlier, I will create a Christmas 2024-2 preview. Just to make sure I stay on the same page, I have a spreadsheet each year of things to do for each sequence. For example, a column might be "sequence candy canes" - referring to a new or modified prop that I need to sequence. One of the columns is which preview is assigned for that sequence. So right now, most of my sequences are still assigned to the preview Christmas 2023-3 because I have not touched them yet (I'm behind this year). Once I start editing the 2023 sequences to become 2024 sequences, they will get assigned to the 2024 preview.
Note for clarity. I said "modifying your preview and save with a new name" and also "create a Christmas 2024-2 preview". Neither of those is the actual steps required to making the new preview. I wanted to clarify the actual steps. In the Sequencer, on the Preview pop-out, select your source preview (maybe Christmas 2023), and use the icon to copy that to a new preview. Give the copy, the new name (for example, Christmas 2024). Then edit the new preview to reflect the changed to props.
