Creating task over 100 days Out

Creating task over 100 days Out

I went to the workflow section in CRM and setup several tasks that auto-generate when we create Quotes, Sales Orders, etc...
I wanted to create one for Invoicing also to create a task that notifies us to send out another Invoice 365 days from now. Our service has an yearly bill cycle to it and wanted to do this so that we don't forget to invoice customers again. When I went to put in 365 in the Workflow Task Days Box, it only allowed 2 digits.
Is there a way that you could expand this to 3 or allow a XX Months Box?
Thanks!
