InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
mkvpropedit can do this, although the command-line options aren't as convenient as mkvmerge, so I'd recommend JMkvpropedit (a GUI built on top of mkvpropedit). Should just be a case of dragging/dropping your files in then adjusting the options.
