Workspace Cost Optimizer hourly/full month conversion

Question

I am considering installing the AWS Workspace optimizer stack to auto move users between full month and hourly based on their  monthly usage count.
https://aws.amazon.com/solutions/implementations/cost-optimizer-for-amazon-workspaces/
**2 Questions**
- If a user is moved from full month back to hourly, what hourly/disconnected stop time does it use?  Does it use the original hourly setting the machine was built with or some other number of hours?  Our users often run projects overnight while disconnected from their machines.  We might set them at 6 to 12 hours for auto-disconnect but never 1 hour.
- I saw that the optimizer can be installed in dry run mode.  What do you have to do to move it from dry run to active mode?  Uninstall and reinstall the stack?
Thanks

1. By default, auto stop time for workspaces is set to 1 hour and when the user is moved from monthly to hourly, the default auto stop time will be applied i.e. 1 hour. 
But it can be changed as per requirements. To set the automatic stop time, select the WorkSpace in the Amazon WorkSpaces console, choose Actions, Modify Running Mode Properties, and then set AutoStop Time (hours).

2. Dry Run Mode parameter for the WCO(Workspace Cost Optimizer) CloudFormation template is by default set to 'Yes'. As outlined in the document provided below, "When you are comfortable with the recommendations provided by the solution and would like these recommendations to be automatically implemented, change the template parameter Dry Run Mode to No".

You can update the WorkSpacesCostOptimizer by: 
a. Open the Cloudformation console https://console.aws.amazon.com/cloudformation/ 
b. Select the stack name allocated for your WorkSpaces Cost Optimizer > Then click 'Update'.
c. Select 'Use current template' and click 'Next'.
d. On the 'Specify stack details' page at 'Parameters', scroll down to 'Launch in Dry Run Mode' and change it to 'No' and Click 'Next'. 
e. On the 'Configure stack options' click 'Next'.
f. On 'Review' page, Kindly read the 'Capabilities' section and tick the 'acknowledge'. Then click 'Update stack'.

Thank you, this answers both my questions.   For the default stop time, is there anything that can be edited manually in the stack  config to manually set a different than 1 hour stop time when users are moved from monthly to hourly?
