Conditional Start Evaluation

When making use of a conditional start, can I evaluate the condition when two seperate variables change. For example, whenever one of these variables (or both) are updated or created, I need a condition to reevaluate if it meets the criteria after variables were changed? See image below.

If so, what is the format of the input, and if not, is there a way I can get the same outcome.

Hi,

It is not possible to specify more than one variable. (1)
What is your use case when var1 and var2 are changed and how often?
Could you add an example of your process so we can give you suggestions which are relevant.
