Not currently from within the Marygold app. This is a feature we are thinking about adding later. As things currently stand the best way to replicate this so it requires the minimum level of effort for you is to create any nudge that uses a trigger event that makes sense for you (eg a nudge on the 1st day of every month).
Then (using this example), we'll notify you on the 1st of every month that you want to save an amount that you have specified as part of the nudge. This notification will have a 'transfer now' button which when pressed will immediately open your Primary Account bank app and pre-load all transaction details for you to authorise the request.
All you need to do is quickly review the payment details and give your consent. That's it! The whole process should take a few seconds.
