For the current beta “Tasks in the Sales Workspace” there is not an option to start a task or group of tasks
It should have the start features found on the tasks view so reps can go through tasks 1 by 1.
Based on feedback we have recieved, this works better than the 3 panel section found on the home summary section of the Sales Workspace.
Hello! My name is Hallie, and I’m an Associate Program Manager on our CXM Team. I’m happy to share that this feature is currently in beta for Sales Professional & Enterprise users! There is a KB with more info on this feature and how it works if interested in a guide. Please continue to leave feedback here for our product teams as you use this beta . 
@HHigbee Thank you for the reply however that beta does not address this submitted idea. The beta continues work on the features noted on the 2nd image and does not offer a way to go through tasks using the feature in the 1st image, which based on our feedback, is a much more effective feature. As it stands now, you have tasks working in 2 different ways based on how you access it in the CRM which leads to confusion with sales team users.
