[feature request] pvoutput

Hi

Just wanted to put in a request to allow the extended data to be updated without the consumption or generation.

It seems that its a requirement in iotawatt to have these fields in order to upload. It is a requirement in the free version of pvoutput that these fields are there, however its not a requirement with the donation mode.

While its not an issue for me now, I am planning on running a 2nd iotawatt and I want to be able to upload just some data from the 2nd to extended fields without the generation or consumption as that information will be taken from the 1st iotawatt.

Thanks
