Is it possible to dynamically name files downloaded after canvas snapshot?

Chums

So I have a 'game' that a user will use over and over again.

when the user finishes they canvas snapshot which then downloads a .png.

At the moment it saves as example.png and then every consecutive snapshot saves as example(1).png, example(3).png and so on.

Is there a way to dynamically name the file from within the game.

Something like a user text input which sets the text of the canv snapshot filename???

Thank you

You can use variables/expressions in this field. An example:

This will set the name to something the user has written into a textfield
