Is the BQL query builder not available in the webui?
Can this be added somehow to allow for batch edits in the web client?

I don't think so but if it was... I could see nothing but bad things happening. Probably better to setup the batch edits yourself and expose a button to run them. May require some custom programming but would be alot safer (and user friendly...)
I was thinking more for service (without WB) or power users only. Typically fewer open ports are always better for IT.
