If my rental's business use percentage goes from 100% to 50% on 8/1/2024, then how can I adjust my rental asset's depreciation for this?

I've seen community comments implying I should close out my original property asset via "Special Handling". Then create a new asset that is 50% business use. But I'm worried this will reset the 27.5 depreciation "clock". Alternatively, it looks like I can edit the original assets Date and Business Percent, but changing the Date to 8/1 + business percent to 50% seems to ignore depreciation I should be getting from before that date.
