Single AWD to monitor 2 channels from different ADCs



As from the title, is it possible to use the same AWD to monitor 2 channels from 2 different ADCs?

Specifically, I have a designed a simple digitizer around a f303k8. ADC1 and ADC2 have been configured in continous mode, with AWD2 and AWD3 as monitors respectively. When one of the AWD triggers an IT, it gets disabled and a DMA transfer starts (100 samples). After DMA, the ADC and AWD are enabled again. 

This approach works, and has been already tested with success. 

Then, I tried setting a single AWD (for example AWD2) to monitor the 2 channels from the 2 ADCs. It seems to work well. However, I did not find mention of the use of a single AWD to monitor channels from 2 different ADCs. Is it feasible, or am I missing something? If possible, it would allow to use 2 AWD to monitor, for example, 4 ADCs of a f303re or similar, which would be interesting for my project. 

Thank you for your time and support,
