Hi there - Thank you for taking the time to give us some feedback! Is the ability to customise a list of clients and saving it for the next time what you're after? In terms of creating the right catchment for your campaign, the easiest way to do that would be to click 'untick all' (by unticking the box to the left of 'Client Name') and then search your clients by name, by the hitting command (cmd) and F key on a mac or control (ctrl) and F key on a PC, and tick them that way. Let us know if that helps! Team Slick x
