clarification request: is it possible to aggregate two or more .rrd files

[paolocrusche]

Dear tbotnz
I'm Paolo Cruschelli from Italy. Thank you for your work on RRDREST, I managed to have it working with my librenms installation.
One question arise. Is it possible to display the aggregated data from two (or more ports)?, in other words is is possible to query two (or more) .rrd files at once?

I know that this is possible with rrdtools (in the following an example which aggregates bandwidth for two files related to two ports:
port-id1170.rrd
port-id1169.rrd

thank you in advance
regards

Paolo
