Doable using an Engagement program. Have 1 stream that has all the content and sends weekly on M-F at like 9am and another stream with nothing in it. Create a smart campaign with recurring schedule for daily M-F at 11:59 pm, smart list is member of EP + constraint Stream is stream 1, flow is change EP stream to Stream 2, wait 1 hour, change EP stream to Stream 1. Essentially you're shifting people out of the sending stream and back into the sending stream which apparently refreshes the next send. The wait 1 hour isn't necessary but probably helps marketo utilise system resources better. To stop converted people from receiving emails, you can create a third stream and use a trigger smart campaign to move people into that stream.
