Workflows - delaying over the weekend

I have a couple of workflows that escalate a case to high priority three days after the Created On date. If the case is created on a Friday they are high priority by the Mon/Tues.

Is there a way to get a workflow to 'take the weekend off'?

I've found a couple of old blogs on this:

• Question answered by Erman Guler in 2011, https://community.dynamics.com/product/crm/f/117/t/53633.aspx 
• And this one from 2008: https://community.dynamics.com/product/crm/f/117/p/9998/24352.aspx#24352 which provides information here  http://www.cub-e.net/post/CRM-workflow-date-update-includes-saturdays-sundays.aspx 

Is there a more up to date method for CRM 2011? I'm not a programmer.

Many thanks
