Unfortunately, I am the in-house developer. I have submitted a Suite Idea : https://nlcorp.app.netsuite.com/app/site/hosting/scriptlet.nl?script=847&deploy=1&whence=# I think the serverWidget module could actually use some extension of features to reach parity with some of the other form options.

As per Richard, the functionality does not exist. So I will spend my next free weekend building it. Will update here.
