Scripted Fields support for Time Series Visual Builder

[fdmsantos]

I'm trying to create a time series visualization with two series to see metrics from servers.

My problem is:
These two series use different json documents. the first serie has a field performancemanager.virtualmachines.name to identify Server name and the second uses inventory.virtualmachines.name to identify Server Name.

I want to filter by Server in Dashboard (Using Global filter or controls). If I use the field from the first serie, will affect the second serie.

Is possible to create a mapping in ES/Kibana between these fields? Something like performancemanager.virtualmachines.name field is linked to inventory.virtualmachines.name, so if a create a global filter to performancemanager.virtualmachines.name, the second serie will use this filter in inventory.virtualmachines.name field?

I have been thinking about using scripted fields
