General issue report

hello everyone.I'm now using idf5.1 in a project to sample two input voltages through adc continuous mode.And the ESP-IDF Programming Guidesays one adc unit can only run in one mode at a time, in same sample frequency. But!!!!! what i need is to sample channel0 quickly and sample channel1 slowly.So how can i do this with same adc uint?Thx a lot.

mcu: esp32s2 framework: idf5.1 adc unit: 1 adc channel: 0, 1

one solution: stop adc continuous mode and read analog value from channel0, then start adc continuous mode to sample from channel1 alternately？
