Web API: limelm.pkey.advancedSearch including extra activation data possible?Solved

Hey! Sorry if this was already answered - I tried my best searching the docs and the forum, I either already have my answer (no) or I just missed it - I was hoping there is another parameter similar to get_features:

Is it possible to also get the extra data (https://wyday.com/limelm/help/extra-data/) of each pkey found based on my search parameters? 

The only way I can currently seem to get the extra data is over limelm.pkey.getDetails - one request per pkey then.

Extra data is the only information missing from what I wanted to handle with advancedSearch. I then just need to rethink my requests.

Thanks!
