[Pharo-dev] GTInspector auto refresh hooks?

Hi. Is there a way in GTInspector presentation to call some special updating block before each of auto refresh operation? I want something like: composite fastTable title: 'Devices'; display: [ devices ]; wantsAutomaticRefresh: true; * beforeUpdateDo: ["rows updating code"]* Imaging my presentation shows database table and I want query updated rows. (I activate updating by GTInspector setEnabledStepRefreshStatus: true). Best regards, Denis
