You are able to create your own custom guidelines within Grasp, by choosing the display location and custom message to be displayed within the native platform:
They can be displayed in blue (information) or as a click-to confirm:
Once created, these guidelines won't be displayed in the Grasp monitoring. Custom guidelines are not actual platform's settings hence this is not possible to retrieve this information through the API.
Custom guidelines include the following types: “change default”, “must confirm budget/dates/times etc.” (except for campaign levels confirm guidelines), checkbox and “automatic/manual placement”. None of these guidelines will be displayed in the monitoring, but will appear within the "issues" view.
