I don't think you should enter a new asset. You should just change the percentage.
You have had it at 75% for years because you only used 3/4 of it. In 2022 you used more than that. In the example you provided you used it for one third of the year so let's use that.
Instead of using 75% for 2022 you will use 75 plus one third of the remaining 25%. One third of 25% is 8.3%. Add that to 75 and you used 83.3% of the house for 2022. Then, when you come back for 2023, you just change it to 100.
I hope your real number isn't a crazy percentage of the year but even if it is it's the only year you have to do the math.
If you do decide to enter a new asset then you will get to start depreciation from a new basis on one quarter of the house. The accumulated depreciation when you sell will be the same, but you won't be able to combine the assets in the future to combine the depreciation. So you'll be entering 75% into one asset and re-entering the 25% into the other asset going forward. That's an unnecessary hassle.
