How to store strings (version name) in influxdb?

Question

Monitoring

We collect a bunch of metrics in influxdb + grafana.
Actually, among the metrics there are some for which you do not need to store a history, just the "current version".
Of course, you can make an additional source in grafana, but I came up with such a bike how to store versions as a tag and insert them into a zero timestamp, so there will be only one version in the table.
will be of the type
INSERT versions,app=myprogram value="myprog-1.0.1" 0
INSERT versions,app=myanotherprogram value="2.3.4" 0
If you do not make an additional source, but use Influxdb, how successful does this solution seem to be?
Can anyone recommend their own, more beautiful crutches?
