Metric-Segment get options on instatiation

Is there anything built into Metric-Segment that could make the GetOptions method fire when the segment is first created, rather than waiting until the user clicks on it for the first time? And follow up question, once the options are loaded, can I make it automatically default to the first one?

I’m working on tailoring the InfluxDB datasource to match the particular schema on my project, and one case that comes up is that there are times when there is only one Measurement in a given database, so I’d like to save my users the trouble of selecting an option when they only have one choice.
