Yep! If you click the three dots (menu) control to the side of a task and select Edit, you'll see a section that says "Repeats" and it'll probably say 'Dailies'. Switch that to 'Weekly'. A section will open up that shows 'Repeat On' with the days of the week as checkboxes. Pick the ones you need and leave the weekend unchecked.

Hope that helps!
