Working around the "Analytics rule start time" for mass deploying using Workspace Manager

Hi!

What are some of your thoughts/experiences of working around the "The Analytics rule start time must be between 10 minutes and 30 days from now" for mass deploying using Workspace Manager?

Lets say I have 100 Analytic rules that I want to deploy to current customer using Workspace manager. This goes fine, but when a new customer arrives 1 month later, I have to redo the start time of all the Analytic rules that hasn't been changed in the last month. Doing this manually is just not an option. What I can see as a possible solution, is to use Repositories at the same time, where I would use a script to mass update the start time for all rules I need. Then sync back to Analytic rules and deploy again to new customer.
