Yeah it would be great if we could check this for a variety of properties.
For example, in terms of a property with a currency value;
If 'property A' is less or equal to 'property B' in an if/then branch, proceed with an action of my choice.
Say we had a £50 gift card amount added to an account, we could check if - 'remaining balance' is less than 'gift card amount' - we can send them an email to remind them of their remaining balance.
