If you have access to custom variables you can also use that to store persistent data to be used in the scenario. These are available on the Pro plan or higher I believe. There are Team variables available as well on the Teams plan that let’s you store a set of custom variables at the team level available to all scenarios in that team.
On Pro plans or higher scenario inputs are also available to be used for on-demand execution of a scenario, this allows you to enter the necessary data to start a scenario using a form input. These can be executed via a separate scenario which includes a Make “Run a scenario” module using the Make app and dynamically enter the necessary data to pre-fill the scenario inputs during execution.
