Hi,
I've been testing the options of central participant database in order to decide if I want to use it to manage participants for future surveys. I've encountered one thing I don't understand though.

From what I've tested you can only add multiple participants at once to a survey by ticking them (or ticking the whole page) and then using the drop box on the left bottom of the page to add them.

Is there a simple option of just adding them all to a survey at once? I know you can change the source code to expand number of participants shown per page, but that makes my browser work slow and sometimes crash. I wondered if maybe there's a simple option that I might've missed.
