XMC4400 ADC Post processing and Boundary Check

I am using an XMC 4400 chip. In the application an ADC input signal set a boundary flag on the ADC_MEASUREMENT_ADV app.
The issue is that the analog signal input seems to be noisy.

Is there a mechanism to do post processing on the ADC and then use the output of this signal as an input to the boundary check (maybe a signal input to another instance of ADC_MEASUREMENT_ADV module)?

The bottleneck now is that we can either choose the ADC output to set a boundary flag or filter the ADC output to get a signal prone to less noise.

Any suggestions regarding this would be highly appreciated.
