By default options hcxdumptool will receive all and hcxpcapngtool will convert all.
Filtering of hashes has to be done later on after conversion to hc22000 either by hcxhashtool or by bash tools.
The hc22000 hash line is explained in section "Working with hash files", here:

BTW:
That is hcxtools philosophy and I have good reasons to do it this way:
Everything that get lost on reception or conversion is lost forever.
