Convert BLE Monitor custom integration from auto discovery to manual

Hi! I am using since a year almost, the custom component ble_monitor. Is a while that bluetooh devices are cumulating and like 95% are even not mine. I would like to convert the current setup (that was done manually through the UI) to the yaml configuration, switching to manual entry for each of the devices I need rather than set it on autodiscovery as it is. Is there any way to keep the “service continuity” without loosing the binding with the current existing entities already registered?
Thanks in advance for your help!
