Hi Ivan,
I just wanted to chime in and confirm that the suggested way would be to use a formula field to help you designate work days and to build your automations to pull from those templates. There isn't a functionality in Automations at this point to specify that you want to use Work Days versus weekends, that is something that relies on the logic available in a formula field to calculate. You would want to go with the types of solutions that Mark and Jason are suggesting to create a template table so that records can be populated with the right dates.
If being able to specify work days in your Automation workflow would be helpful though I would suggest putting that in as a User Voice request. The Quick Base User voice can most easily be accessed from the My Apps page in Quick Base by clicking on the orange Feedback tab that appears on the right of the page or at
http://quickbase.uservoice.com by signing in with your Quick Base credentials. This way it is on the mind of our Product Team as they continue to look at how users are automating their workflows. Sorry there isn't a simpler path I could recommend to you and thank you for your time.
Also if you do make a User Voice request it can be helpful to post a link to that request here so other community members in the future with the same need can add their votes as well.
