Support for variables

Does Webflow have any support for variables? a variable is a placeholder that gets instantiated on rendering, dynamically. For instance, an editor would write:

The session starts on $$DayOne, and ends on $$LastDay

$$DayOne and $$LastDay are variables. They get their values for instance from a dictionary / list in Settings.

Nope. It does not. You can create variables in custom code and then use them as needed of course in that code.
