MQTT Binding, multiple things sharing a topic

Hi I am starting to use the tasmota RF bridge, unfortunately all received codes are sent via the same topic. The bridge itself cannot find out which codes come from the same thing, even thou it seems workable.

Is it possible to define multiple things that use the same topic, and perhaps they can “filter” which particular messages are for each thing?

Yes, using the REGEX Transformation Service.

Note that it is the Thing Channels which subscribe and publish to the topics.
