different years showing different content in a name slicer

[henry24007]

is there any dax or by any method that can make different years showing different content by a name slicer?

For example, I have 20 department in total, but for "ABC" and "AA" department, there is a change in 2023. ABC department and AA department is going to merge and become "ABCAA" in 2023, in my slicer, I don't want to show ABC and AA department having the slicer option of 2023, they can only in 2021 and 2022 data. And for ABCAA, it can only be viewed in 2023 in slicer.

For ABC and AA, I only want them to have 2022 and 2021:

For ABCAA,  I only want it to have 2023 in my slicer

in department slicer, I want ABC, AA, ABCAA to exist in the same time:
