[Take Recorder] Unable to layer record different actor properties in same sequence

Is it possible at all to layer record different properties of the same Blueprint actor (source) one at a time and using the same Sequence with Take Recorder? For example, if a BP actor has two properties (variables in a Blueprint) I would like to be able to record one of them, then stop and select the same Sequence so I can record the second property while playing the first one, layering the properties one at a time. So far even if I select the same Sequence to record on top (following the documentation under Using Layered Take Recording), Take Recorder creates a new sequence if the same object (source) is being recorded. Selecting each property individually in the source’s Recorded Properties settings for each pass doesn’t work either. It seems that layered take recording only works as long as the sources being recorded are different actors for each layer. Is this correct?
