help with FlexAsio Usb MIC

[Mulberry03]

Hello everyone, I wanted to ask for help if anyone understands well on the subject (I'm new in this world), it turns out that I'm trying to use a USB microphone that I use on my computer, the problem is that I can not select multiple inputs in flexasio (ver 0.35), this clearly is not connected directly to the audio interface, it is directly to the pc, is there any way to select in the inputs the microphone and the input of the sound interface to record the microphone and the audio from flexasio? I am using REAPER

FlexASIO can only use one input device and one output device at a time. There is no way to select multiple inputs or multiple outputs. See #58.

On Asio , this is a feature to mix between inputs , it's really sad we can't do it on FlexAsio , for example me , i play my guitar using line in (using my motherboard line in input) and mic using my hyper x mic (which is plugged via USB) , if only we can use both of them so i can play and sing on my daw
