Can I book a connecting flight to Phuket on the same day as my arrival in Bangkok under the sandbox scheme?

The original poster inquires about the possibility of booking a connecting flight from Bangkok to Phuket under the sandbox scheme, should quarantine requirements change. Multiple responses confirm that transit through Bangkok is not permitted and highlight that Bangkok is currently utilizing the sandbox model, suggesting that if quarantine measures are altered, it may still allow for the sandbox option in Bangkok itself.
