Pipo onseg marker at end of buffer?


I see there is an attribute for inserting a marker at the beginning of the buffer in an onseg process (although it seems to me to be inverted, so that 0 adds a buffer and 1 removes it, no?). Is there an equivalent to add a marker at the end of the buffer? And if not, what would be the best strategy? The “getduration” message doesn’t seem to be recognized by mubu.track — or am I sending it to the wrong place?

Many thanks!
