Basic IMACRO Set on Loop and Randomized Timer

We need an imacro set up in Google Chrome. The imacro is very basic and we have gotten it to do the task but we'd like it set up on a loop with a randomized timer. Features: Navigate to the website Click one element Refresh Loop set on a randomized time with the ability to input the min and max *Input the min and max time remotely - so that we can deploy the imacro on multiple instances and manage the global timer settings for all instances. This will also include an input for ability to run the loop X amount of times or set it to infinite. --- Ideally we would like to have a settings page where we could navigate to the url and change the settings from anywhere or If this will cost too much we can also just upload a file every time we want to update settings *(please quote us for both options) Any responses that do not mention both options will not be considered
