Is there any way to include the default value in the workflow variable list. I think this would be VERY useful.
Yes you can set most variables with a default value, so for instance if you have 3 variables and the workflow starts these variables will not be empty.
I think the question rather is, if you can display these default values on the workflow variables overview.
Afaik you cannot. But you can suggest this feature to be included in a future release of nintex: Customer Feedback for Nintex
I think this feature would be useful, good idea! You will receive my vote
Just in case Phillip's answer is not what you are after.
Below is how you set a default value for a workflow variable.
For Nintex Workflow on-prem, you can do this via Workflow Settings->Workflow variables for variables that support default values
(variable such as collection variables do not support default value)
For Nintex Workflow O365, you cannot set a default value for any variables.
I believe this was added to user voice here:
