Set Block Sample Time

KrakenSDR is running on Pi5 with October 24-005 release. I would like to take bearing from a master with seven clients sending on the same frequency in burst mode. Eight stations with different angle of arrival (AOA). The KrakenSDR samples by default in 436 ms blocks. Therefore, I must reduce block time from 436 ms down to 50-80 ms. Maybe the write time into the log must be more often executed than once a second. Yes, it’s clear the logfile will extend very fast, but I would like to trace a master with seven clients sending/bursting on the same frequency with different AOA. Where can I set in GUI block sample time and write period? Please send advice.
